Answer:
arc ABC = 196°
∠DCQ = 47°
Step-by-step explanation:
arc AD = 70°
∠D = 1/2 arc ABC = 98°
arc ABC = 98° * 2 = 196°
arc CD = 360° - arc AD - arc ABC = 360°-70°-196° = 94°
tangent chord angle DCQ = 1/2 arc CD = 1/2 * 94° = 47°
Let the number be x, the square of x is x^2, then
The product of the square of x and 5 is 5x^2.

Explanation-
I just know :)
∠4 is also 75 (interior opp angles)
