Answer:
The value of x = 10.
Step-by-step explanation:
From the given triangle,
- The value of angle M = (3x + 28)°
- The value of angle K = (5x - 18)°
- The value of angle L = 90°
We know that the sum of a triangle is 180°.
i.e.
K + L + M = 180°
(5x - 18)° + 90° + (3x + 28)° = 180°

Therefore, the value of x = 10
Answer:
100
Step-by-step explanation:
cut the figure into 2 sides and multiply 8x5 then once you have cut it in half its not 10x12 it is 5x12 you get 40 and 60 then add together to get 100
2x^2 + 16x + 34 = 0
x^2 + 8x + 17 = 0
x^2 + 8x + 16 = -17 + 16 = -1
(x + 4)^2 = -1
x + 4 = sqrt(-1) = ±i
x = -4 <span>±</span> i
D is the answer because it says each and that’s a key word to understand that it’s multiplying
