A triangle is 180°, so the 3 angles should add up to 180°.
To find m∠R, you can do this:
m∠S + m∠R + m∠T = 180°
56° + m∠R + 30° = 180°
m∠R + 86° = 180° Subtract 56 and 30 on both sides
m∠R = 94°
Answer:
76 is the correct one. So you surely go for it
3=6 ; 6+8=180
(2x-5)+(x+5)=180
X=60
6=115, 8=65
Hope that answer can help you!
There are 6 choose 3 possibilities (combinations).
6C3 = 6!/(6-3)!3!
= 6•5•4/(3•2•1)
= 120/6
= 20
With 20 possibilities, there is a 1 in 20 chance that she will choose her favorite three.
The answer is Option C. 1/20.
The population of the town in 1982 is 29995.2.
<h3>What is a percentage?</h3>
A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given, the population in 2020 is 49992.
40 percentage of population
= 40 % of 49992
= 40 x 49992/100
= 19996.8
Now the population in 1982
= population in 2020 - 40% of population in 1982
= 49992 - 19996.8
= 29995.2
Therefore the population in 1982 is 29995.2.
