Answer:
x° = 149°
Step-by-step explanation:
According to the <u>Triangle Sum Theorem</u>, the sum of the measures of the angles in every triangle is 180°. Since we are given two angles with measures of m < 86° and m < 63°, then the third angle must be:
m < 86° + m < 63° + m < (angle 3) = 180°
149° + m < ? = 180°
Subtract 149° from both sides to solve for m < (angle 3)
149° - 149° + m < (angle 3) = 180° - 149°
m < ? = 31°
Therefore, the measure of the third angle is 31°.
To find x°, we can reference the <u>Triangle Exterior Angle Postulate</u>, which states that the measure of an exterior angle of a triangle is equal to the sum of the measures of the remote interior angles.
In other words, the measure of x° = m < 86° + m < 63°
x° = 149°
By the way, m< (angle 3) and x° are also supplementary angles whose sum equal 180°:
x° + m < (angle 3) = 180°
149° + 31° = 180°
Answer:
7
Step-by-step explanation:
No. of pizza Ronnie stacked = 0.25 × 40
= 10
No. of pizza Mack stacked = 9
No. of pizza Kim stacked = 
× 40
= 14
No. of pizza Ada stacked = 40 - 10 - 9 - 14
= 7

Step-by-step explanation:
its a square all sides of the square are the same so 48 divided by 4 is 12
5 points is not a lot of points
Answer:
7.2 cm
Step-by-step explanation
The area of a rectangle is calculated by multiplying the width and the length together. Therefore:
13 multiplied by x = 93.6
x = 93.6 divided by 13
x= 7.2
