Answer:
h= 7/6 mm
Step-by-step explanation:
hello :
the area is : A= (b+B)×h/2
calculate h the height : 2A = (b+B)×h
so: h = 2A/(b+B)
you have : A=21/5 and b= 3 and B= 21/5
h= 2(21/5)/(3+21/5)
h= (42/5) /(36/5)
h= 42/36
h= 7/6 mm

Find the measure of the missing angle in this isosceles triangle.
Answers
The measure of the missing angle(a) in the isosceles triangle(two sides and angle equal) is 70 degrees.
What is an Isosceles triangle?
An Isosceles triangle is a triangle that has two of it sides equal to each other and two of it angles equal to each other.
The base angle of an isosceles triangle are equal. Therefore, let's find angle a in the triangle.
55 + 55 + a = 180
Recall the sum of angle in a triangle is 180 degrees.
110 + a = 180
subtract 110 from both sides
110 - 110 + a = 180 - 110
a = 70 degrees

A bag contains 30 cookies: 9 vanilla, 9 chocolate, and 12 oatmeal. What is the probability that a chocolate is randomly selected
Answers
Answer:
30% for chocolate
Step-by-step explanation:
9÷30= 30% 0.3 vanilla
9÷30=30% 0.3 chocolate
12÷30=40% 0.4 oatmeal
The probability of choosing chocolate is 0.30.
What is the probability?Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event.
Number of total cookies = 30
Number of vanilla = 9
Number of chocolate = 9
Number of oatmeal = 12
The probability that chocolate is randomly selected is;
Probability of choosing a chocolate = Number of chocolate / Number of total cookies
Probability of chosen a chocolate = 9 / 30
Probability of chosen a chocolate = 3 / 10
Probability of chosen a chocolate = 0.30
Hence, the probability of choosing chocolate is 0.30.

A triangle has sides with lengths of 63 miles, 64 miles, and 85 miles. Is it a right triangle? Yes or no?
Answers
Answer:
no it is not a right angled triangle.
Step-by-step explanation:
forthetra
If this is a right triangle (meaning one of the angles in the triangle is 90 degrees) then the lengths of the sides should make the formula true.
a^2 + b^2 = c^2 (c being the longest side or hypotenuse)
so plug in the lengths and prove or disprove the statement.
(63)^2 + (64)^2 = (85)^2
3969 + 4096 = 7225
8065 = 7225 false
The answer is NO it is not a right triangle.

Answers
Using proportions, it is found that 889 students would be expected to prefer painting over scultuprue.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, 20 out of 45 students prefer painting over sculpture. Out of 2000 students, how many students would be expected to prefer painting? The rule of three is given by:
20 - 45
n - 2000
Applying cross multiplication:
45n = 20 x 2000
n = (20 x 2000)/45
n = 889.
889 students would be expected to prefer painting over scultuprue.

The probability that the number selected is the square of a natural number will be [tex]\frac{1}{5}[/tex].
What is probability?Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1.
Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.
P is the probability
F(E) is the favorable event
T(E)is the total event
The probability is found as;
[tex]\rm P = \frac{F(E)}{T(E)} \\\\ \rm P = \frac{4}{20)} \\\\ \rm P = \frac{1}{5}[/tex]
