The answer would be 3 and 2. Complementary means when you add two angles together, they equal 90° or a right angle.
Step-by-step explanation:
solve the equation with formula : SOH, CAH,TOA.
from the above, SOH is to be used to answer the question.
so, Sin∆=Opp/Hyp
∆=41°
Opposite=AB
Hyp= 13.5cm
sin 41°=AB/13.5
sin41°=0.6560
0.6560= AB/13.5
AB=13.5*0.6560
AB=8.856cm
to three significant figure AB=8.86 cm approximately
Answer:
x=-25
Step-by-step explanation:
1. Add -15 to both sides
50=-2x
2. Divide -2 to both sides
-25
Final Answer:
-25
(Let me know if you still don't understand
So, an isosceles triangle has 2 equal sides, we will call them x.
The base can be modeled by 3+x
So, the perimeter is equal to x + 3+x + x
So
15.6 = 3x + 3
12.6 = 3x
4.2 = x
So, the lengths of the sides are 4.2, 4.2, 7.2
