Answer:
52.4%
Step-by-step explanation:
Simply multiply the value with 100 to find the percentage
thus 0.524× 100 = 52.4%
we are given
S=80
RS=2
we can use tangent formula


now, we can find QR

we will get
...........Answer
(1.6x + 3.25) + (0.3x + 0.5)
combine like terms
1.6x+.3x +3.25 +.5
Result:
1.9 x + 3.75
X(x+2)=224x2+2x-224=0(x+16)(x-14) =0x= 16 or 14
the answer is 16 and 14
For this case we can use the law of the sine to solve the problem.
We have then:

From here, we clear the value of x.
We have then:

Rewriting we have:
Answer:
The angle R is given by:
x = 68 degrees
