Answer:
32°
Step-by-step explanation:
The model forms a triangle. The sum of the angles of a triangle is 180°. Solve with the following equation:
? + 90 + 58 = 180
? + 148 = 180
? = 32
Therefore, the angle of elevation is 32°.
If both classes contain 167 students then we add them 167+167= 334
Answer:
Step-by-step explanation:
x^2-8x+x-8
x(x-8)+1(x-8)
(x+1)(x-8)
The negative number is x=-1
Dividing fractions is easy
