The answer is A endurance
Answer:
30°
Step-by-step explanation:
Let the measure of the missing angle be x°
Therefore, by interior angle sum postulate of a triangle:
x + 60° + 90° = 180°
x + 150° = 180°
x = 180° - 150°
x = 30°
Thus the measure of the missing angle is 30°.
Answer:
- -7.5x -12.5, x < -1
- 7.5x +2.5, x ≥ -1
Step-by-step explanation:
The absolute value function changes slope at its vertex. Here, that vertex is translated to x = -1. To the left of that point, the function is equivalent to one that negates its argument:
|x| = -x . . . for x < 0
|x| = x . . . for x ≥ 0
<u>for (x+1) < 0</u>
y = -7.5(x +1) -5 = -7.5x -12.5
<u>for (x+1) ≥ 0</u>
y = 7.5(x +1) -5 = 7.5x +2.5
This means we can write the piecewise function as ...

<span> The </span>lateral area<span> of a three-dimensional solid is the area of all the lateral face. It is calculated as follows:
LA = hP
LA = h(2(w) + 2(l))
LA = 3(2(12) + 2(7))
LA = 114 m^2
The surface area is calculated as follows:
SA = LA + 2B
SA =LA + 2(w)(l)
SA = 114 + 2(12)(7)
SA = 282 m^2
Therefore, the correct answer is option A.</span>
