Answer:
3. AGH= 150
4. CHF= 110
Step-by-step explanation:
3. AGH corresponds to CHF, so they equal the same. AGH = 150
4. BGE is vertical to AGH, so they equal the same AGH = 110. AGH corresponds to CHF, so they equal the same. CHF=110.
Combine like terms the solve. For example:
5x + 20x = 100
25x = 100
/25 = /25
x =4
