Question

HELP NEEDED ASAP!! Please CAN SOMEONE HELP

Answer 1

y = 23º

x = 20 cm

Explanation:

Cos∅ = adj/hyp

cosy = 48/52

∅ = arccos48/52

use calculator

∅ = 22.619864948040426

Rounded

∅ = 23º

----------------------------------

a² + b² = c²

x² + 48² = 52²

x² = 52² - 48²

x² = 400

x = 20 cm

Answer 2

Part 1:

y= 23

Part 2:

x=20

Explanation:

Part 1:

cos(y) = 48/52

y=cos^-1(48/52)

y=22.619864948~23

Part 2:

48^2+x^2=52^2

x^2=2704-2304

x=sqrt(400)

x=20 or -20.

A negative length makes no sense, so x=20
