Add the two known angles: 45° + 45° = 90°
Now we know the third angles. Which is a 90 degree angle. If a triangle has a 90 degree angle, then it is a right angle triangle.
We know that
[surface area]=2*[area of the base]+[perimeter of the base]*height
area of the base=15*13----> 195 in²
perimeter of the base=2*[15+13]----> 56 in
height=7 in
so
[surface area]=2*[195]+[56]*7-----> 782 in²
the answer is
782 in²
Answer:
I believe the answer is B
Step-by-step explanation:
The answer is b, because it is linear and x and y have a proportional relationship with x increasing by 2 and y increasing by 4. So the slope is 2/4 or 1/2 making it a proportional relationship.
The set {−1,0,1} is closed under multiplication
