Xét tam giác AHB vuông tại H

Suy ra BH = AH.tanA = 12,9.tan61°=23,37

Ta có BC= HC+ HB= 9+23,27 =32,27

Diện tích tam giác ABC = 1/2 × AH ×BC= 1/2 ×12,9×32,27=208,1415

PERSON WHO GETS IT RIGHT GETS BRAINLIEST
saul85 [17]

Step-by-step explanation:

Let x = number of games that Alex played

The total money that he spent C is given by

C = 2x + 15

If he spent $45, then we can write

45 = 2x + 15

Solving for x, we get

2x = 45 - 15 = 30 \Rightarrow x = 15

This means that Alex played 15 games.
