An exterior angle is equal to the sum of the two opposite inside angles.

T + 31 = t + t-29

Simplify:

T + 31 = 2t -29

Add 29 to both sides:

T + 60 = 2t

Subtract 1t from both sides:

T = 60

<h2>Answer:</h2>

Using the distributive property, we can simplify the expression.

4 × 3 = 12

4 × $\frac{1}{4}$ = 1

4 × $(-\frac{1}{2})$ = -2

Here is the simplified expression:

$12 + c - 2d$

Alenkasestr [34]

Answer:

$\alpha = 60°,\:\beta = 30°, \: 90°$

Step-by-step explanation:

$Arccos( \frac{ \sqrt{3} }{2} ) = \beta \\ Arccos( \cos \: 30 \degree ) = \beta \\30 \degree = \beta \\ \therefore \: \alpha = 60 \degree \\ remaining \: angle = 90 \degree \\$
