Answer:

110 degrees.

Step-by-step explanation:

Angle A + Angle B = 180 degrees.

Therefore, 5x+20+9x-92=180

When you solve you get 14x=252 or x=18

When you plug that into A you get 5(18)+20=110

Therefore, A=110 degrees

Gnoma [55]

Answer:

1.2 * 10^3

Step-by-step explanation:

3.12 * 10^8

=========

2.6 * 10^5

Start by doing 3.12 / 1.6 = 1.2 and that is the correct number of sig digs.

Now get the power on the 10. When dividing, the powers subtract.

10^(8 - 5)

10^ 3

The answer is 1.2 * 10^3
