not that one sorry 
The measure of an acute angle is less than 90 degrees. If an acute angle measures 3x - 15, then the inequality to represent its measure is 3x - 15 < 90. Solve to find the measure of x.
	A.	x < 25
	B.	x < 35
	C.	x < 45

.sam. · Answer

Just solve x,
3x-15<90

3x<15+90

3x<105

(3x)/(3)<(105)/(3)

x<(105)/(3)

x<35

callisto · Answer

measured angle < 90
and the measured angle = 3x-15
so combine them, you'll get
3x-15<95
3x<95+15
can you solve it yourself?
