Answer:
The answer is 40.
Step-by-step explanation:
Both of the angles given are congruent. 2y-10=70. To get y, you must multiply 2 and 40 together, making 80. Then you subtract it by 10, making it 70 degrees.
Answer: the number is 1
assume the number to be x. so according to the question
2 x a number is subtracted from 7 and the result is 5
the equation will be:
7-2x=5
now we have to solve for x
7-2x=5
2x=7-5
2x=2
x=1

Step-by-step explanation:
A data summation is a collection of values.
The total surface area of the triangular prism that has a height of h and the side length of a is given below.
![\rm a(\dfrac{\sqrt3}{2} \ a + 3h)](https://tex.z-dn.net/?f=%5Crm%20a%28%5Cdfrac%7B%5Csqrt3%7D%7B2%7D%20%5C%20a%20%2B%203h%29)
<h3>What is a triangular prism?</h3>
A triangular prism is a closed solid that has two parallel triangular bases connected by a rectangle surface.
A box is in the shape of an equilateral triangular prism.
If the box is to be covered with paper on its lateral sides.
Let a be the side length of the equilateral triangle and h be the height of the prism.
Then the surface area of the triangular prism will be
Surface area = 2 × area of triangle + 3 × area of the rectangle
The area of the triangle will be
![\rm Area\ of\ triangle = \dfrac{\sqrt{3}a^2}{4}](https://tex.z-dn.net/?f=%5Crm%20Area%5C%20of%5C%20triangle%20%3D%20%5Cdfrac%7B%5Csqrt%7B3%7Da%5E2%7D%7B4%7D)
The area of the rectangle will be
![\rm Area \ of \ rectangle = a \ h](https://tex.z-dn.net/?f=%5Crm%20Area%20%5C%20of%20%5C%20rectangle%20%3D%20a%20%5C%20h)
Then the total surface area will be
![\rm Surface\ area = 2 \times \dfrac{\sqrt3 a^2 }{4} + 3 ah\\\\\\Surface\ area = a(\dfrac{\sqrt3}{2} \ a + 3h)](https://tex.z-dn.net/?f=%5Crm%20Surface%5C%20area%20%3D%20%202%20%5Ctimes%20%5Cdfrac%7B%5Csqrt3%20a%5E2%20%7D%7B4%7D%20%2B%203%20ah%5C%5C%5C%5C%5C%5CSurface%5C%20area%20%3D%20%20a%28%5Cdfrac%7B%5Csqrt3%7D%7B2%7D%20%5C%20a%20%2B%203h%29)
