Answer:

∠3 = 34°

Step-by-step explanation:

There are (at least) two ways you can get there:

∠3 is complementary to ∠6, which is a vertical angle with ∠1. So, ∠3 = 90°-56° = 34°
∠3 is complementary to ∠4, which is a corresponding angle with ∠1. So, ∠3 = 90°-56° = 34°.

Convert 83% into a decimal<br> can you guy help me to do that

PilotLPTM [1.2K]

To convert a percentage to decimal form, you need to divide the number in the percent by 100. In reality, that just looks like moving the decimal point to the left two places.

83% / 100 = 0.83

83% in decimal form is 0.83.
Hope that helped! =)
