Mathematics

Answer:

Yes, you can

Step-by-step explanation:

The standard form of the equation of a parabola is y=ax^2+bx+c

When given three points, you substitute each point into the equation to obtain 3 simultaneous linear equations.

You then solve the three equations simultaneously to find the values of the constants a,b, and c.

You then substitute these constants into y=ax^2+bx+c

In ΔGHI, the measure of ∠I=90°, the measure of ∠G=62°, and GH = 96 feet. Find the length of IG to the nearest tenth of a foot.
alexandr402 [8]

Answer:

45.1feet

Step-by-step explanation:

Given the following

∠I=90°

∠G=62°, and

GH = 96 feet = Hypotenuse

Required

IG = Adjacent side

Using the SOH CAH TOA identity

Cos theta = Adj/hyp

Cos 62 =IG/96

IG = 96cos62

IG = 96(0.4695)

IG = 45.1feet

Hence the length of IG to the nearest tenth is 45.1feet
