(2x+9) + (10x+15) = 180°
2x+9 + 10x+15 = 180°
Add up liked terms
12x+24 = 180°
-24 on both sides
12x = 156°
/12 on both sides
x = 13
< ABC = (2x+9)
< ABC = 2(13)+9
Answer : < ABC = 35°
< CBD = (10x+15)
< CBD = 10(13)+15
Answer: < CBD = 145°

Answer:
flip the shape to the opposite y axis then traverse the the shape 5 units up on the y axis.
Answer:
AU=20 units
Step-by-step explanation:
We are given that
AT=20 units
Point A is the incenter of triangle PQR.
Incenter is that point where three angle bisector of triangle meets.
AR is the bisector of angle R of triangle PQR.
Therefore,
All right triangles are similar when two triangles are similar then the ratio of their corresponding sides are equal.
Right angled triangle ATP and Right triangle AUP are similar.
Therefore,
units
AP is the angle bisector of angle P of triangle PQR
Using the value of angle x
Hence, the measure of angle QPA=35 degree
