Answer:
2.a)31°
b)135°
3.a)72°
Step-by-step explanation:
2a) Angles in a straight line add up to 180°
180-62=118°
since in an isosceles triangle base angles are equal 62÷2=31°
b)sum of interior angles=180(n-2)
180(8-2)=1080°
each angle is 1080÷8=135°
3.a) Exterior angle=360/n
=360÷5=72° each
Answer:
2.5
Step-by-step explanation:
The answer is simple
First find the angle measures of first triangle:
statement:
we know that the sum of 45 and 30 sums up to the opposite angle and that is equal to 75, then to find the next remaining angle:
180-(75+20)=85
The you find the supplement of 85:
180-85=95
so x = 95
Hope it helps
Answer:
the answer is 8
Step-by-step explanation: so first what you want to do is you want to set up the equation 18x-41. then you want to do 15x because of the 15 per hour. then you minus 17. so your equation is 18x-41=15x-17 then the answer to that is 8 hours
Answer:
If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent.
