Answer:

51°

Step-by-step explanation:

Given

<QPR = 39°

<PQR = 90° ( inscribed angle in semi circle)

Now

<QPR + <PQR + <PRQ = 180° { being sum of angles of triangle)

39° + 90° + <PRQ = 180°

<PRQ = 180° - 39° - 90°

<PRQ = 51°

Hope it will help :)

A narrow arch supporting a stone bridge is in the shape of half of an ellipse and is 24 meters long and 8 meters high. A person
fenix001 [56]

Answer:

X=17.9m

Step-by-step explanation:

Length of arc L_a=24m

Height of arc H_a=8m

Tet the length on the ground be

2a=24\\ a=12m

Generally the Pythagoras equation is mathematically given by

a^2=b^2+c^2

c^2=a^2+b^2

c^2=12^2+8^2

c^2=144^2+64^2

c=8.9

Therefore the distance between he person throwing the ball and the point on the ground at which the ball first strikes X

X=2c\\X=2*8.9

X=17.9m
