Answer:

A) 150

Step-by-step explanation:

All the angles in a triangle must add up to a total of 180 degrees.

So we can make an equation as given below:

20+10+?=180

30+?=180

?=150

So the missing angle is 150 degrees

What is -11 + 3(b + 5) = 7

IRISSAK [1]

Answer:

b=1

Step-by-step explanation:

$\sf -11 + 3(b + 5) = 7$

First, let's regroup, terms,

$\sf 3(b+5)-11=7$

Add 11 to both sides,

$\sf 3(b+5)=7+11$

Simplify, 7+11 = 18,

$\sf 3(b+5)=18$

Now, divide both sides by 3,

$\sf b+5=\frac{18}{3}$

Simplify, 18/3 = 6,

$\sf b+5=6$

Subtract 5 from both sides,

$\sf b=6-5$

$\sf b=1$

Hope it helps! :)
