Which of the following statements are true? Select all that apply. In a triangle ABC, angle A is (2x + 1) degree, angle B is x degree, and angle C is (x + 15) degree.
A. (4x + 16)° = 180°
B. x° = 49°
C. m∠A = 99°
D. From smallest to largest: ∠B, ∠C, ∠A

the true statements are A, D

Step-by-step explanation:

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
