Answer:
35/4 =8¾
Step-by-step explanation:
using pythagoras theorem
hyp²=opp²+adj²
recall that tanX= opp/adj
taking our opposite side to be 3 and the adjacent side to be 4 , the hyp² = 3²+4²
hypotenuse = 5
recall also that , sinX = opposite /hypotenuse
= 3/5
CosX= adjacent /hypotenuse
=4/5
so we've known tanx = 3/4 cosX = 4/5 sinx= 3/5
substitute these values into your equation
it will give us 3/5 + 4/5 divided by 4/5 ×(1-4/5)
=35/4 = 8¾
Answer:
75 cm
Step-by-step explanation:
To find the area of a traingle you use the following equation
b*h*.5
We know that the height of the triange is three times the base and that the area is 937.5
This means that
b*3b*.5=937.5
We can combine this and get 1.5b^2=937.5
We can then divide by 1.5 to get b by itself
b^2=625
Then take the square root for our answer and get b=25 (while be also can be -25 it doesn't make sense to have a negative answer in the context of this problem)
So we know that b=25 and that h=3b which means that the height is 75 cm
