Answer:

The sum of interior angles in a triangle is 180°.

So we just have to add Al the angles and equate them to 189°

Step-by-step explanation:

$70 + 65 + x + 35 = 180 \\ 135 + 35 + x = 180 \\ 170 + x = 180 \\ x = 180 - 170 \\ x = 10$

Answer:

Step-by-step explanation:

Using the rule of exponents

$\frac{a^{m} }{a^{n} }$ = $a^{(m-n)}$

Note that 8 = 2³, thus

$\frac{2^{5} }{8}$

= $\frac{2^{5} }{2^{3} }$

= $2^{(5-3)}$

= 2²

Step-by-step explanation:

Step 1: Define

-4w - 3 = 9

3w + 4

Step 2: Solve for w

[Addition Property of Equality] Add 3 on both sides: -4w = 12
[Division Property of Equality] Divide -4 on both sides: w = -3

Step 3: Evaluate

Substitute in w: 3(-3) + 4
Multiply: -9 + 4
Add: -5
