Answer:
4950
Step-by-step explanation:
you round down from the 50
For problem #4 the answer is 100°. The triangle are congruent meaning the angles that are given both of the triangle have to have the same angles.
The triangle sum theorem is all triangles have a 180° . All the 3 angles = 180.
They gave you two angles of the triangle. So add the two angles and find the difference of 180.
50+30=80
180-80=100°
#5 set those 2 angles equal. Because the A corresponds to Q. Solve for X and plug in your x value
Answer:
Option (3)
Step-by-step explanation:
Therefore, Option (3) will be the correct option.
Answer:
Correct option is

Let AB and CD be two lines Intersecting at O, such that, ∠AOD=90
∘
Now, ∠AOD=∠COB=90
∘
(Vertically opposite angles)
⟹∠AOD+∠DOB=180
o
(Angles on a straight line)
⟹90+∠DOB=180
o
∠DOB=90
∘
∠DOB=∠AOC=90
∘
(Vertically opposite angles)
Thus, all angles are 90

Answer:
A = 27.7
Step-by-step explanation:
Knowing that an equilateral triangle has 3 equal side lengths, we can create our area and perimeter equations! x will be one of the side lengths
- A = (1/2)(b*h)
- all angles are 60
- Using angles: sin(60) =
- A =
P = 3x = 24
x = 8
A =
A = 27.7
