15 7 ÷ 15 4 is equal to . 15 11 1 15 3

15^7 ÷ 15^4 is equal to 15^3.

Step-by-step explanation:

∠JKL = 65°

Explanation:

We are given that:

∠JKL = 3x + 5

∠JKM = 45°

∠MKL = x°

Now, we know that ∠JKL is the summation of ∠JKM and ∠MKL

Therefore:

∠JKL = ∠JKM + ∠MKL

Substitute with the givens in the above equation and solve for x:

∠JKL = ∠JKM + ∠MKL

3x + 5 = 45° + x

3x - x = 45 - 5

2x = 40

x = 20

This means that:

∠JKL = 3x + 5 = 3(20) + 5 = 65°

∠JKM = 45°

∠MKL = x° = 20°

Check:

∠JKL = ∠JKM + ∠MKL

∠JKL = 45° + 20° = 65° > verified

Hope this helps :)
