Answer:
m∠XMN = 80°
Step-by-step explanation:
you know that:
4x + 5 + 6x - 10 = 145
solve for x:
10x - 5 = 145
10x = 150
x = 15
Use this information to solve for m∠XMN
6(15) - 10
90 - 10
80
m∠XMN = 80°
So a right triangle is 90° and we have a 45° angle every triangle=180° so 90+43=133
180-133=47° the other angle is 47°
Angles in triangle add to 180 degrees
20x=180
x=9
Angle ABC is the top one
8x9=72
Answer:
91.46m
Step-by-step explanation:
The length of 100 yard football field in meters.
From the dimension given,
1 yard = 3 feet
Therefore,
100 yard = x feet
1 yard = 3 feet
100 yard = x feet
X = (100 × 3) / 1
X = 300 feet.
But,
1 metre = 3.28feet
X metre = 300 feet
X = (300 × 1) / 3.28
X = 91.46m
Therefore, 100 yard football field is equal to 91.46m
-8y + 4(11y - 3) =
-8y + 44y - 12 =
36y - 12 <==
