If ∠rst = 65, m∠qst = 2x, and m∠qsr= 3x – 10, what is the value of x?

35

13

65

15

x = 15

Step-by-step explanation:

Given: ∠RST = 65, m∠QST = 2x, and m∠QSR= 3x – 10

∠QST + ∠QSR = ∠RST

Plug in

2x  + 3x – 10 = 65

Combine like terms

5x - 10 = 65

Add 10 to both sides

5x = 75

Divide both sides by 5

x = 15

So x = 15

£56

step-by-step explanation:

u divide 24 by 3 and u get 8 so if u do 8 time 7 or 8+8+8+8+8+8+8 u get 56 and 56 divided by 7 is 8.
