Answer:
Option A. x = 8
Step-by-step explanation:
Please see attached photo.
From the attached photo,
we shall determine the value of y. This can be obtained by using pythagoras theory as illustrated below:
(√80)² = 8² + y²
80 = 64 + y²
Collect like terms
80 – 64 = y²
16 = y²
Take the square root of both side
y = √16
y = 4
Finally, we shall determine the value of x. This can be obtained as follow:
From the attached photo,
x = 2y
but:
y = 4
Therefore,
x = 2y
x = 2 × 4
x = 8
If the number only has 2 digits, it could only be 91, because since the tens digit is 8 more than the ones digit, the tens digit is greater than or equal to 8. it cannot be 10 or more, because that would make the number over 100, leaving only 8 and 9. If the tens digit is 8, the ones digit is zero, and since it cannot be zero, then the tens digit must be 9, leaving the ones digit to be 1. So, the final answer is 91.
Answer:
114
Step-by-step explanation:
find the solution below
First we find X:
3x+x=180
4x=180
x=180/4
x=45.
3x=135
135+y=180
y=180-135
y=45
45+z=180
z=180-45
z=135
In conclusion, x=45, 3x=135, y=45 and z =135
Also note that the opposite angles are equal so you can just find 3x and that will be equal to z and x will be equal to y.
Hope this helped
