5:2 in simplest form. 10:4 in normal
1. You multiply both sides by a
2. You're done!!!
Answer:
m = 5
Step-by-step explanation:
We are told that the two triangles are similar. Thus, each side of the larger triangle is the same multiple of the corresponding side in the smaller triangle.
Thus, 12 = k(7.2), where k is the constant of proportionality.
Solving this for k, we get
k = 12/7.2 = 1 2/3
Thus, side m is 1 2/3 times 3, or 5/3 times 3, or just 5.
m = 5
Answer:
64°
Step-by-step explanation:
∠RQP = 46°
∠PRQ = 180° - 110° = 70°
∠PRQ + ∠RQP + <u>∠RPQ</u> = 180°
70° + 46 + <u>∠RPQ</u> = 180°
116° + <u>∠RPQ</u> = 180°
Find <u>∠RPQ</u>
<u>∠RPQ</u> = 180° - 116° = 64°
Step-by-step explanation:
The exterior angle is the sum of the opposite interior angles of the triangle.
Therefore, m<D +m<C = 118°
=> 8y+3 +3y+5 = 118°
=> 11y = 118° - 8°
=> 11 y = 110°
=> y = 10°
m<D = 8y+3
= 8(10)+3 = 83°
m<C= 3(10)+5 = 35°
m<DEC = 180° -118° = 62°
