Answer:
Step-by-step explanation:
26 divided by 33
Equals: 0.78787878787 etc
%: 78 or 79 percent
Given :
Length of one of the equal sides of an isosceles triangle = 3x+2
Then, length of the other equal side will also be = 3x+2
Length of the unequal side of this isosceles triangle = 14
Formula for finding the perimeter of an isosceles triangle :

A formula for finding the perimeter of this isosceles triangle :

Bringing all like terms together we get :



Thus, the formula = 6x+18
Therefore, a formula to find the perimeter of this isosceles triangle = <u>6x+18</u>
We can use the Sine Law:
a / sin A = b / sin B
16 / sin 22° = 25 / sin B
16 / 0.3746 = 25 / sin B
sin B = 25 · 0.3746 / 16
sin B = 0.5853
∠B = sin^(-1) 0.5853
∠B = 35.83° ≈ 35.8°
Answer: b. 35.8°
Answer:
9.230095943 or 9.2
Step-by-step explanation:
Trigonometry: sine, cosine, tang: Sohcahtoa
O: opposite(side from angle)
H: hypotenuse(side opposite from 90*)
A: Adgacent(side from angle)
Use scientific calculator: tang(40*) x 11 = 9.230095943
