Hope this helps!!!
Answer:
Length of other base = 42 cm
Step-by-step explanation:
h = 24 cm
One of its base a = 30 cm
![Area=864cm^{2}\\\\\frac{(a+b)*h}{2}=864\\\\\frac{(30+b)*24}{2}=864\\\\(30+b)*12=864\\\\30+b=\frac{864}{12}\\\\30+b=72](https://tex.z-dn.net/?f=Area%3D864cm%5E%7B2%7D%5C%5C%5C%5C%5Cfrac%7B%28a%2Bb%29%2Ah%7D%7B2%7D%3D864%5C%5C%5C%5C%5Cfrac%7B%2830%2Bb%29%2A24%7D%7B2%7D%3D864%5C%5C%5C%5C%2830%2Bb%29%2A12%3D864%5C%5C%5C%5C30%2Bb%3D%5Cfrac%7B864%7D%7B12%7D%5C%5C%5C%5C30%2Bb%3D72)

Answer:
y = 8º
y = 8º
Step-by-step explanation:
Given:
(10x - 61)º
(18y + 5)º
(x + 10)º
Find:
x and y
Computation:
(10x - 61) + (x + 10) = 180
11x - 51 = 180
11x = 231
x = 21º
(10x - 61)º = (18y + 5)º [Vertical opposite angle]
10x - 61 = 18y + 5
10x - 18y = 66
5(21) - 9y = 33
y = 8º
