I’m sorry but I’m also struggling
Answer: 11
Step-by-step explanation:
Complementary angles mean both angles sum 90°, then:
(3x + 2)° + 5x° = 90°
3x° + 2° + 5x° = 90°
8x° + 2° = 90°
8x° = 88°
x = 11
Confirmation:
(3x + 2)° 5x°
(3(11) + 2)° 5(11)x°
(33 + 2)° 55x°
35°
35° + 55° = 90°
Step-by-step explanation:
solve for x
![5x + 35 + 2x - 15 = 90 \\ 7x + 20 = 90 \\ 7x = 70 \\ x = 10](https://tex.z-dn.net/?f=5x%20%2B%2035%20%2B%202x%20-%2015%20%3D%2090%20%5C%5C%207x%20%2B%2020%20%3D%2090%20%5C%5C%207x%20%3D%2070%20%5C%5C%20x%20%3D%2010)
For y
![y = 180 - 65 \\ y = 115](https://tex.z-dn.net/?f=y%20%3D%20180%20-%2065%20%20%5C%5C%20y%20%3D%20115)
For z
![5z - 18 = z + 22 \\ 4z = 40 \\ z = 10](https://tex.z-dn.net/?f=5z%20-%2018%20%3D%20z%20%2B%2022%20%5C%5C%204z%20%3D%2040%20%5C%5C%20z%20%3D%2010)
