Answer:
Step-by-step explanation:
According the Triangle sum theorem:
m<T + m<U + m<V =180
x + 2x + x + 80 = 180
solve: x=25
Therefore m<T = 25, m<U = 50, and m<V = 105
Answer:
Pranav had 36 posters on Monday.
Step-by-step explanation:
We can make up an equation to demonstrate this problem.
We don't know how many posters he had on Monday, so we can represent that amount as x. We know Pranav buys 10 more, so now it's x + 10. We also know that after he bought 10 more posters, half of all his posters got destroyed, leaving him with 23.
The final equation is:
(x + 10) ÷ 2 =23
We now need to isolate the x, so we multiply both sides by 2 to get rid of it.
It now equals:
x + 10 =46
Finally we subtract 10 from both sides.
Our answer is:
x =36
12 would be the numerical coefficient
Answer:
8.1
Step-by-step explanation:
use phythagoras theorem
since you have a hypotenuse and one known side you must equate the unknown side with the known sides and square two known side ,9^2-4^2= 62 then you must get the unknown side by introducing a square root and rounding off to the nearest decimal
