Question

Find z if possible please?

Answer 1

Answer:

z = 30

Step-by-step explanation:

so your going to do a ratio to the big triangle to small

ratio be z+10 over 52 to 10 over 13

cross multiply 52 x 10 = 13(z+10)

520 = 13z + 130 subtract 130 from both sides

13z = 390 divide by 13 to get z = 30
