Answer:
133*3+90*3+30*p
Step-by-step explanation:
add all that up then divide it by three
Answer:
p=43°
Step-by-step explanation:
We know that the sum of angles inside the triangle is 180 degree
One angle is P, we find other two angles
Angles in a straight line is 180 degree.
angle adjacent to 133 is 180-133=47
angle adjacent to 90 is 180-90=90
To find out P, we add all the angle and make it equal to 180 degree
p + 47+90= 180
p+137= 180
Subtract 137 on both sides
p=43°
