Answer:
∠ GDH = 67.5°
Step-by-step explanation:
The measure of the chord- chord angle GDH is half the sum of the measures of the arcs intercepted by the angle and its vertical angle.
∠ GDH = 
(GH + EF) = (90 + 45)° = 0.5 × 135° = 67.5°
Answer.
Step-by-step explanation:
Hey I would like to help, do you have anymore Information??
Like how long he was on the phone for?
It should be noted that the expansion of the equation (ac+b-d)(a² - c) will be a³c + ac² + a²b - bc - a²d + cd.
<h3>How to illustrate the information?</h3>
It should be noted that an equation is used to show the relationship that occur between the variables that are illustrated.
In this case, it should be noted that the equation
(ac+b-d)(a² - c) will be solved accordingly. This will be:
(ac+b-d)(a² - c)
Open the parentheses
a³c + ac² + a²b - bc - a²d + cd
Therefore, it should be noted that the expansion of the equation (ac+b-d)(a² - c) will be a³c + ac² + a²b - bc - a²d + cd.
