Answer:
A. 6(n + 8) = 19
Step-by-step explanation:
Look for key words.
6 <u>times</u> the <u>sum</u> of a number and 8 <u>is</u> nineteen.
From these key words it is clear that the solution is 19, you are adding an unknown number (a<em> variable</em>, which we will represent with x) to 8, and multiplying our (x+8) by 6.
Write out the equation.
6(n + 8) = 19
Don't know how clear this is, but I hope it helped you figure this out!
We can use the formula below to find the area of the segment:
Since the diameter is given as 6 cm, the radius will be half of that, which is 3 cm.
Using π = 3.14, we can solve as
Therefore, the area of the sector is 14.13 square centimeters.
The answer is 8/27 just so you know
Answer:
32
Step-by-step explanation:
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∘
