Answer:
x=13
m∠A = 46° m∠B = m∠C = 67°
Step-by-step explanation:
ΔABC : isosceles
vertex ∠A = 4x -6
∠B = ∠C = 5x + 2
∠A + ∠B + ∠C = 180° = (4x -6) + 2 * (5x + 2) = 14x - 2
14x = 182 x = 13
∠A = 46° ∠B = ∠C = 67°
Answer: x=1
Step-by-step explanation:
-6=-5x-1
-5=-5x
x=1
Answer:
262,144
Step-by-step explanation:
(-0.5 * 4)^18
(-2)^18
262,144
Answer: 262,144
Answer: 14.8units²
Step-by-step explanation:
The formula for calculate the area of a triangle is:
Where b () is the base and h () is the height.
The formula for calculate the area of a semicircle is:
Where r is the radius.
As you can see, the diameter is 5 units, then the radius is:
The area of the figure is the sum of the area of the triangle and the area of the semicircle.
Then, the result is:
Answer: 5
Step-by-step explanation:
1. 3x+2=17
2. 3x+2-2=17-2 ( we subtract 2 from both sides)
3. then we simplify 3x=15
4. \frac{3x}{3}=\frac{15}{3} then i divide both sides by 3
5. and as we simplify, x=5
