I need help on these as well

For number 5, the triangle sum theorem states that all angles inside of a triangle must add up to 180 degrees, so we have 30+90+66+x. Right angles are 90 degrees.

186+x=180

x=-6

For number 6, same rule applies here.

60+30x+90 = 180.

150+30x=180

x=1

its 86

Step-by-step explanation:

what? ?

what type of question is thiss

step-by-step explanation:

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
