Answer:
4 3/8
Step-by-step explanation:
1 1/4 * 3 1/2
Answer:
considering angle a to 40
b and c.....= 50 both
Answer:
20
Step-by-step explanation:
interior angle + exterior angle = 180°
162° + exterior angle = 180° ( subtract 162° from both sides )
exterior angle = 18°
the sum of the exterior angles of a polygon = 360° , then
number of sides = 360° ÷ 18° = 20
Answer:
Angles congruent to ∠8 are ∠1, 4, 5

Since both triangles are similar triangles, you are able to find the scale factor through the perimeter.
Perimeter of the 3 4 5 triangle is 12cm.
Scale factor = 30/12
= 2.5
Multiply the scale factor with the 3 4 5 triangle.
3 x 2.5 = 7.5 cm
4 x 2.5 = 10 cm
5 x 2.5 = 12.5 cm
To summarize, all 3 new values should sum up to 30cm.
