100*x I think I’m sorry that’s a poor answer I have done this in years
Answer:
12.
m∠ACB = 180° - 58° - 78° = 44°
m∠DCE = 180° - 85° - 60° = 35°
m∠BCD = 180° - 44° - 35° = 101°
13.
Base on the picture, we know that:
x° + 2x° + 3x° = 180°
6x° = 180°
x° = 180° ÷ 6 = 30°
=> m∠K = 2x° = 2 × 30° = 60°
=> m∠L = 3x° = 3 × 30° = 90°
=> m∠KML = x° = 30°
m∠LMN = 60° + 90° = 150°
Answer:
133
Step-by-step explanation:
The two angles add to a straight line
PQR + RQS = PQS
3x-5 + x+1 = 180
Combine like terms
4x -4 =180
Add 4 to each side
4x -4+4 = 180+4
4x =184
Divide each side by 4
4x/4 =184/4
x =46
We want to find PQR
PQR = 3x-5
= 3*46 - 5
= 138 -5
= 133
Set up a proportion:
kid/dad = kid/dad
8/9 = 5.5/dad
Cross multiply to solve proportions:
8*dad = 9*5.5
8*dad = 49.5
dad = 6.1875 feet
They want inches so multiply by 12:
74.25 inches
They want "nearest inch" so:
Dad is 74 inches tall.
