Given that ABC is a right angle triangle with m∠C=90°, m∠B=75° and AB=12cm.
Area of triangle =
=
So we need to find BC,AC now.
To find them let us take sinB and cosB.
SinB =
BC = 12* cos B = 12* cos 75
So, area =
= 72*sin(75)*cos(75)
= 36*(2sin(75)cos(75))
= 36*sin(150) = 18
Hence area of triangle is 18
Hope this helps tbh sorry I was a little late btw (:
Answer:
The answer would be A. 55.
Step-by-step explanation:
For the 35% you would take your 200 and divide it by 2 and have two 100's. Since 35% is out of 100% you could take 35 from each 100 and add them together to get 70.
For the 3/8 you would divide and get .375 then you would multiply that by 200 which would give you 75 yellow tags. Then you would add 75 and 70 and get 145. Then subtract 145 from 200 to get 55. Therefore there would be 55 red tags.
Hello! A way we could solve this equation is to divide 714 by three and then multiply the quotient by 2 to get the number of men that attended. 714/3 is 238. There were 238 women that attended the concert. 238 * 2 is 476. 476 + 238 = 714. There. There were 476 men that attended the concert.
37.7 is the circumference, 113.1 is the area, use a calculator for more in depth looks.
Answer:
More girls chose canoeing as their favorite outdoor activity than those who chose skiing.
More boys chose skiing as their favorite outdoor activity than girls.
There were more boys surveyed than girls.
More students chose camping as their favorite outdoor activity than the combined number of students who chose canoeing or skiing.
Step-by-step explanation:
The last answer:-
Number choosing camping = 81 and the number choosing canoeing or fishing = 35 + 45 = 80.
