My guess is 30 because every triangle has to add up to 180. 90+60 is 150 180-150 is 30
Answer:
8/625
Step-by-step explanation:
bc i guessed and its says 8/625
132msq.
square=6×6×3
triangle= 1/2×4×6×2
add both
answer we will get 132 metre sq.
Answer:
yes ; 17.5 ft
Step-by-step explanation:
Triangle PRQ is isosceles
the base angle are equals
we know two legs, so we can find the tangent of angle x
tan = opposite/adjacent
tan = 7/16 = 0.4375
the angle x measure 23.6 degrees circa (we can calculate this with the button tan -1 on the calculator)
the roof is safe
B we can use the Phytagorean theorem to solve this
PR = √16^2 + 7^2 = √256 + 49 = 17,46... = 17.5 ft
I don’t really understand what this is asking but the formula for circumference is C= πd Remember that diameter (width of the circle) is double the radius (half the width of the circle) and π is about 3.14
Hope this helped
