Answer:

56 deg

Step-by-step explanation:

All internal angles of a triangle add up to 180 degrees

hence,

∠O + ∠R + ∠F = 180

x + (x+43) + (x-31) = 180

x + x+43 + x -31 = 180

3x+ 12 = 180

3x = 180 - 12 = 168

x = 168/3 = 56 deg

stiks02 [169]

Answer:

184,499 will fit, Yes

Step-by-step explanation:

Proportions

We'll use proportions to answer the question and find the number of students fit into a building of 300 ft x 300 ft. The area of the building is

$300\ in\times 300\ in=90000\ in^2$

We are given a factor of 2.05 students per square feet, thus the number of students that fit into the building is

$2.05\cdot 90000\ in^2=184500$

Since 184500 is greater than 142551 people required, they easily fit into that space.

The closest answer is

184,499 will fit, Yes

The length of a rectangle is 5 yd longer than its width.

romanna [79]

Answer:

w = 13yd, l = 18yd

Step-by-step explanation:

let x be width, so x+5 = length

Perimeter is sum of all 4 sides, and since opposite sides equal in rectangle,

P = 2(l+w)

= 2(x+5 +x)

= 4x + 10

Since perimeter is give as 62yd, equation is

4x + 10 = 62

4x = 52

x = 13
