Step-by-step explanation:
Calculate the unknown sides and angles of the triangle ABC given.
Given the final answer correct to three significant figures.
C= 25.7° , b= 3.5cm, a = 6cm
Step-by-step explanation:
to understand thisyou need to know about:law of sinelaw of cosinePEMDASlet's solve:there are 3 ways to solve SAS triangle
use The Law of Cosines to calculate the unknown side,then use The Law of Sines to find the smaller of the other two anglesand then use the three angles add to 180° to find the last angle.first figure out [tex]\angle C [/tex]
to do so we will use the formula of law of cosine of C angle
[tex] {c}^{2} = {a}^{2} + {b}^{2} - 2ab.\cos(C) [/tex]
substitute the given values of a,b and [tex]\angle C[/tex]
[tex] \sf{c}^{2} = {6 }^{2} + {3.5}^{2} - 2.6.(3.5). \cos( {25.7}^{ \circ} ) [/tex]
simplify squares:
[tex]c^{2}=36+12.25-42.\cos(25.7^{\circ})[/tex]
simplify addition:
[tex]c^{2}=48.25-42.\cos(25.7^{\circ})[/tex]
square root both sides
[tex] \sf \: \sqrt{ {c}^{2} } = \sqrt{ 48.25-42. \cos(25.7^{\circ})}[/tex]
simplify:
therefore
[tex]\bold{c=3.23}[/tex]
use law of sine to figure out angle A
[tex] \dfrac{6}{\sin( \angle \: A) } = \dfrac{3.23}{\sin(25.7)} [/tex]
therefore
[tex]\bold{\angle A=53.66°}[/tex](use calculater to simplify it)
therefore
[tex]\angle B\: is\: 180^{o}-25.70^{o}-53.66^{o}[/tex]
[tex]\bold{= 100.64}[/tex]

Answer:
Missing Truck Value=6
Missing Car Value=45
Step-by-step explanation:
Since the ratio of trucks to cars is 2:3, you do 3 times 3 equals 9. Since all 3 ratios needed to be equal, we have to do 2 times 3 which is 6. That is how you get the truck value. We do the same to get the car value. 6 times 5 is equal to 30, so we do 9 times 5 too. That gives you 45.

Can someone help please!
Answer:
Step-by-step explanation:
extend the line on the 5ft side to create a triangle and a rectangle.
Area of a rectangle is l x b
10 x 4 = 40ft^2
Area of a triangle is 1/2 base x height
the height of the triangle will be 10 - 5 = 5ft
the base of the triangle will be 12 - 4 = 8
1/2 (8) x (5)
20ft^2
Total area = area of triangle + area of rectangle
Total area = 20ft^2 + 40ft^2
Total area = 60 ft^2

Why do you think there is a limit on the number of times you can withdraw or transfer money in your savings account?
Answer:
I think that there is a limit on the number of times you can withdraw or transfer money in your savings account because banks only maintain a small percentage of the money people deposit on the savings accounts and most of the money is used for loans and they need to limit that to be able to have enough reserves to cover the withdrawals. If they don't put a limit people can try to withdraw all the money at the same time and the bank would not have the funds to cover that.

In triangle ABC, the length of side AB is 10 inches and the length of side BC is 17 inches. Which of the following could be the length of side AC?
Answer:
16 inches
Step-by-step explanation:
The length of the side AC is 16 inches.
Calculation of the length of side AC:
Since
we know that two side lengths of a triangle as x and y (x greater than y), the third side z should satisfy the inequality
So, it can be like
x - y ≤ z ≤ x + y
Also,
The side lengths are x=17 and y=10,
So,
17 - 10 ≤ z ≤ 17 + 10
7 ≤ z ≤ 27
Therefore, the AC should be 16 inches.

Find two integers whose sum is -20 and product is 99
Answer:
Step-by-step explanation:
let the integers be x and y
x+y=-20
y=-20-x
xy=99
x(-20-x)=99
-20x-x²=99
x²+20x+99=0
x²+11x+9x+99=0
x(x+11)+9(x+11)=0
(x+11)(x+9)=0
x=-11,-9
when x=-11
-11+y=-20
y=-20=11=-9
when x=-9
-9+y=-20
y=-20+9=-11
so integers are -11,-9
