Answer:
x = 6.5
Step-by-step explanation:
Since all angles in a triangle adds up to 180°, we have:
10x - 10 + 10x + 8 + 8x = 180
28x - 2 = 180
28x = 182
x = 182/28 or 6.5
If the sum of the first and last is 64, their average is 32. They will have a difference of 6, so the first number is 29 and the last is 35. The numbers are therefore 29, 31, 33, 35.
1. As M is the midsegment JM / JK = 1/2
By similar triangles JM/JK = 1/2 = x / 12
2x = 12 so x = 6 answer
2. By the same reasoning as above
x / (x + 9 ) = 8.5 / 17 = 1/2
2x = x + 9
x = 9
Answer x = 9
Answer:
D
12²
Step-by-step explanation:
Given in the question, an integer = 144
To find the exponential form 144 we will do factorisation
The prime factorisation of 144 is
2 × 2 × 2 × 2 × 3 × 3
So the exponential form is 2
× 3²
The other way is
√144 = 12
which means
12² = 144
