Find the measure of angle A
please help

firstly find x

10x+85+8x+5=180

10x+8x+85+5=180

18x+90=180

18x=180-90

18x=90(dived by 18 both sides)

x=5

Step-by-step explanation:

8x+5(make the value of x)

8x5+5

45

angle A is equal to 45

5x+10 is the correct one

hope this

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.
