∠A and \angle B∠B are supplementary angles. If m\angle A=(4x-30)^{\circ}∠A=(4x−30)
user100 [1]

Answer:

the measure of ∠A. is 87∘

Step-by-step explanation:

Two angles are said to be supplementary angles if the sum of those angles is 180 degrees.

_________________________________________________

Given

∠A=(4x−30) ∘

∠B=(4x−14) ∘

Fir angles to be supplementary

∠A + ∠B = 180

(4x−30) ∘ + (4x−14) ∘ = 180∘

(8x -54 )∘ = 180∘

=> 8x =  180∘ +  54∘= 234∘

=> x = 234∘/8 = 29.25∘

Thus,

∠A=(4x−30) ∘

∠A=(4*29.25−30) ∘ =( 117 - 30 ) ∘ = 87∘

Thus,

the measure of ∠A. is 87∘

A square bathroom has an area of 100m2. What is the distance from
inysia [295]

Answer:

10\sqrt{2}  meters

Step-by-step explanation:

The bathroom is in the shape of a square. The area of square is given as:

A=s^2

Where

s is the length of the side

We know area is 100, thus:

A=s^2\\100=s^2\\s=\sqrt{100} \\s=10

The side length of the square is 10 meters.

The distance from one corner to another corner is known as the "diagonal".

We use the formula below to get the distance of the diagonal:

d=\sqrt{2}s

Where

d is the length of diagonal

s is the length of side [here, 10]

THus, length of diagonal is:

d=\sqrt{2}(10)\\ d=10\sqrt{2} meters
