Answer : 27 triangles
Explanation : Considering if one triangle has 1/18 area
n triangle have n x 1/18
To composed an area of 3/2 we need to get 27 triangles each having an area of 1/18
Since 27 ×1/18
= 3/2
Answer:
A
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin30° = , then
sin30° = = = ( cross- multiply )
2x = 8 ( divide both sides by 2 )
x = 4
Answer:
(X-8) and (x+1)
Step-by-step explanation:
If we multibly then (X-8) (x+1)=0 =x^2-7x-8=0
Answer:
Option A
Step-by-step explanation:
Answer:
∠ U = 70°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
120° is an exterior angle of the circle , then
∠ U + 50° = 120° ( subtract 50° from both sides )
∠ U = 70°
