Answer:
Equation: 2x + 5 + 6x + 15 = 92
Solution: x = 9
m∠A =23° m∠B = 69°
Step-by-step explanation:
measure of ∠B = 3(2x + 5) = 6x + 15
The sum of the angles = 92 = 2x + 5 + 6x + 15
92 = 8x + 20
72 = 8x
x = 9
m∠A = 2(9) + 5 = 18 + 5 = 23
m∠B = 6(9) + 15 = 54 + 15 = 69
Check: 23 + 69 = 92 and 23(3) = 69
Answer:Because both result in the equation 8x = 400 which simplifies to 50.

Answer:
Area of square = 289r²
Step-by-step explanation:
Given:
Side of square = 17r
Find:
Area of square
Computation:
Area of square = side²
Area of square = (17r)²
Area of square = 289r²
Answer:
- root (7²+8²)=10.63
- root (10²-5²)=8.66
- root (11²-3²)=10.58
- root (18²+15²)=23.43
Step-by-step explanation:
a²+b² = c²
a = side of right triangle
b = side of right triangle
c = hypotenuse
