I NEED HELP ASAP! THANKS! :)

The length of GI is 90 units.

Step-by-step explanation:

You have to use Cosine Rule,

Let a = GI units = x units,

Let b = 60 units,

Let c = 42 units,

Let A = 123°,

We are given:

GH = 60

HI = 42

∠H = 123°

We can use the law of cosines to solve:

GI² = HI² + GH² - 2 * HI * GH * cos ∠H

GI² = 42² + 60² - 2 * 60 * 42 * cos ∠123

GI² = 1,764 + 3,600 - 2 * 60 * 42 * -0.545

GI² = 8,110.8

√GI² = √8,110.8

GI ≈ 90.06

Therefore, the length of GI is approzimately 90.06 units.

Best of Luck!

42%

step-by-step explanation:

we know,

total people = 60

total males = 25

percentage of males

= 25/60 × 100

= 25/6 × 10

= 25/3 × 5

= 125 / 3

= 41.

rounding of = 42%
