M<3 is (3x + 4) and m<5 is (2x +11)
butalik [34]

Answer:

Part 1) Option C. Same side interior angles

Part 2) Option A. (3x+4)+(2x+11)=180\°

Part 3) Option B. m

Step-by-step explanation:

Part 1) we know that

If p and q are parallel

then

m<3 and m<5 are consecutive interior angles or Same side interior angles

and

m

Part 2) we know that

m -----> by consecutive interior angles (supplementary angles)

we have that

m

m

so

substitute

(3x+4)+(2x+11)=180\°

Part 3) Find the measure of angle 5

we know that

(3x+4)+(2x+11)=180\°

Solve for x

5x+15\°=180\°

5x=180\°-15\°

x=165\°/5\°=33\°

m

substitute the value of x

m

the length of the shadow of a pole on level ground increases by 90m when the angle of elevation of the sun changes from 58 degre
Anarel [89]

Answer:

The height of the pole is 167 m

Step-by-step explanation:

The given parameters are;

Increase  in the length of the shadow = 90 m

Initial angle of elevation of the Sun = 58°

Final angle of elevation of the Sun = 36°

We have a triangle formed by the change in the length of the shadow and the rays from the two angle of elevation to the top of the pole giving an angle 22° opposite to the increase  in the length of the shadow  

We have by sin rule;

90/(sin (22°)  = (Initial ray from the top of the pole to the end of the shadow's length)/(sin(122°)

Let the initial ray from the top of the pole to the end of the shadow's length = l₁

90/(sin (22°)  = l₁/(sin(122°)

l₁ = 90/(sin (22°) ×(sin(122°) = 283.3 m

Therefore;

The height of the pole = 283.3 m × sin(36°) = 166.52 m

The height of the pole= 167 m to three significant figures.
