Answer:
95 degrees
Step-by-step explanation:
a triangle's interior angles add up to 180 add the two known angles subtract by 180 and you get the answer.
55 + 30 = 85
180 - 85 = 95
95 degrees
The lateral surface area of a cylinder is just the long side connecting the bases, whereas the total surface area includes both the lateral surface area and area of the two circular bases.
(Imagine a rectangle with the circumfrence of the base as one side and the height as the other being folded around)
(Plus the area of two circles)
The literal difference between surface areas would be the two bases 2πr² if you need that.
Answer: AAS
Step-by-step explanation:
In the given triangles, there are two angles such as and and one non included side as 16 cm of both triangles are equal or congruent.
Thus, by AAS postulate of congruence both the triangles are congruent without establishing any additional information.
- <em>The AAS postulate says that if two angles and the non-included side one triangle are congruent to two angles and the non-included side of another triangle, then these two triangles are congruent.</em>
Answer:
65 km/hr
Step-by-step explanation:
The average of numbers can be calculated by adding them up and dividing that by how many numbers there are.
Here, we have two numbers. Therefore, we first add them (55+75 = 130) and then divide by 2 because there are 2 numbers, so 130/2 = 65
