Answer:
20%
Since Emily gave 15 of her buttons out of 75, it's just 15/75 or 1/5 which is 20
Step-by-step explanation:
Answer:
the measure of all the angles within a triangle is = 180 degrees.
the two given angle measures are 70 and 90.
90+70= 160 making the remaining angle = 20 degrees
the two triangles are similar to each other, so they have the same angle measurements. making the measure of angle 1 = 20 degrees
Answer:
60 degrees
Step-by-step explanation:
Similar shapes have the same angles but different side lengths.
180-135= 45. The angles of a scalene triangle add up to 180 so therefore add the 2 angles and minutes your answer from 180
