I believe the correct answer from the choices listed above is the last option. The measure of an exterior angle at the vertex of a polygon never equals the measure of the adjacent interior angle. Rather, they are always supplementary angles.
Hope this answers the question. Have a nice day.
Answer: Surface area of a triangular prism = 2*Area of Base (triangle) + Perimeter of Base (triangle)*Height
Step-by-step explanation: The sum of the areas of all the sides of the triangular prism is equal to the surface area. Thus, if you add all the areas of the sides you will get the surface area. The equation above is a faster way to do it.
Answer:0
Step-by-step explanation:
m=y2-y1/x2-x1
m=-8--8/-10--9=0/-1=0
The slope of the line is 0
Perimeter is the sum of all a shapes sides.
with that in mind, we know a rectangle has four sides. with 2 pairs being the same.
The length as told is, 5 centimeters less than two times the width. Two times the width would be 2w and five less than that would be minus five. so the length is 2w - 5
now to find the perimeter we do two times the width + two times the length.
2w + 2(2w -5) = 80.
Distribute: 2w + 4w - 10 = 80
Add ten to both sides and combine the 2w & 4w:
6w = 90
Divide both sides by 6: w = 15.
with this we know the width is 15. to find length plug in 15 to the 2w - 5 equation.
2(15) - 5 = 30 - 5 = 25.
Slap on the units and width = 15 cm, length = 25 cm
When you are 10 years ,your sister will be 10/2 = 5 years
10 - 5 = 5
Your sister is 5 years younger to you
After 90 years your age will be 100 years.
After 90 years your sister's age will be 5+90 = 95 years
Correct option A
Hope This Helps You!
