Find the value of x
in the figure below
Answer:
x = 29
Step-by-step explanation:
I think this because they give you 78 degrees. The angle across from it (3x - 9) must equal 78 degrees as well. So solve as (3x - 9) = 78. 78 + 9 is 87. 87 divided by 3 is 29.
Hope it helps and is correct!

The perimeters of two similar triangles are 25 cm and 15 cm respectively. If one side of the first
triangle is 9 cm, find the corresponding side of the second triangle.
plz guys hrlp me if you solve i will make brainliest
Answer:
5.4cm
Step-by-step explanation:
In similar triangles, the perimeter of the triangles will be in the ratio of their corresponding sides.
The ratio of their perimeter is
perimeterofΔ2 15
--------------------- = -------------
perimeterofΔ1 25
So, the side of triangle 2 will be
9 * 15 15
---------------- = --------------
sideofΔ2 25
=
⟹side of Δ2= 25 / 9∗15 =5.4.

Answer:
x = 0.954
Step-by-step explanation:
We apply pythagorean to find x
(4-x)² = 1.2² + 2.8²
(4-x)² = 9.28
✓(4-x)² = ✓(9.28)²
4 - x = 3.046
- x = 3.046 - 4
- x = -0.954
x = 0.954

Factors are simply numbers that can divide another number without leaving a remainder.
The statement that 2z is an integer factor of y is true
The statement is given as:
The factor of number y is given as z.
From the above statement, we have:
If z is a factor of y, then 2z would also be a factor of y

Under her cell phone plan, Sofia pays a flat cost of $58.50 per month and $4 per gigabyte. She wants to keep her bill at $76.50 per month. Write and solve an equation that can be used to determine gg, the number of gigabytes of data Sofia can use while staying within her budget.
Answer:
To stay within budget, she must use 4.5 gigabytes.
Step-by-step explanation:
Giving the following information:
Under her cell phone plan, Sofia pays a flat cost of $58.50 per month and $4 per gigabyte. She wants to keep her bill at $76.50 per month.
First, we need to establish the total cost formula:
Total cost= 58.5 + 4*x
x= number of gigabytes
Now, we isolate x:
76.5= 58.5 + 4x
18/4= x
4.5= x
To stay within budget, she must use 4.5 gigabytes.

Find y.
Round to the nearest tenth:
29
500 ft
Answer:
y ≈ 242.4 ft
Step-by-step explanation:
The angle on the right of the triangle = 29° ( alternate angle )
Using the sine ratio in the right triangle
sin29° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{y}{500}[/tex] ( multiply both sides by 500 )
500 × sin29° = y , then
y ≈ 242.4 ft ( to the nearest tenth )

Find the volume of a triangular prism where the base length is 6 ft, the base height is 5 ft, and the prism height is 7 ft.
Given:
The base length is 6 ft, the base height is 5 ft, and the prism height is 7 ft.
To find:
The volume of the triangular prism.
Solution:
Base of a triangular prism is a triangle with base length 6ft and height 5 ft.
Area of a triangle is
[tex]Area=\dfrac{1}{2}\times Base\times Height[/tex]
So, the area of the base is
[tex]B=\dfrac{1}{2}\times 6\times 5[/tex]
[tex]B=\dfrac{30}{2}[/tex]
[tex]B=15[/tex]
Now, the volume of a triangular prism is
[tex]V=Bh[/tex]
Where, B is the base area and h is the height of the prism.
Putting B=15 and h=7, we get
[tex]V=(15)(7)[/tex]
[tex]V=105[/tex]
Therefore, the volume of the triangular prism is 105 cubic ft.
