Answer:
22.5°
Step-by-step explanation:
We know that the measure of straight line is 180° . Therefore the sum of all angles will be 180° .
⇒ 90° + x + 3x = 180°
⇒ 90° + 4x = 180°
⇒ 4x = 90°
⇒ x = 90°/4
⇒ x = 22.5°
<h3>
<u>Hence</u><u> </u><u>the</u><u> value</u><u> of</u><u> x</u><u> is</u><u> </u><u>2</u><u>2</u><u>.</u><u>5</u><u>°</u><u> </u></h3>
The speed of the faster cyclist will be 30 miles/hour.
<em><u>Explanation</u></em>
One cyclist is 3 times as fast as the other.
Lets assume that the speed of the slower cyclist is miles/hour.
So, the <u>speed of the faster cyclist</u> will be: miles/hour.
They start riding toward each other at the same time and meet 2 hours later.
We know that,
So, the <u>distance traveled by slower cyclist</u> in 2 hours miles and the <u>distance traveled by faster cyclist</u> miles.
Given that, they were 80 miles apart at the starting. So, the equation will be.....
So, the speed of the faster cyclist will be: (3×10)= 30 miles/hour.
Let x be the length.
Then the perimeter is given by the formula : 2(20+x)=40+2x.
Area of the dance floor:
Answer:
M = (2L -K)/7N
Step-by-step explanation:
in order to solve for m in the expression K=2L-7NM , we will first combine the like terms and then express m int erms of k,n and l.
<u>solution</u>
K=2L-7NM
combine the like terms
K + 7NM = 2L
7NM = 2L -K
Divide both sides by 7N
7NM/7N = (2L -K)/7N
M = (2L -K)/7N
Therefore from the question K=2L-7NM M is evaluated to be M = (2L -K)/7N
