What is the measure of ehg?

Answers

Answer 1

Answer:

Answer:

The measure of EHG = 120°

Step-by-step explanation:

There are three vectors originating from point H and joining three points E, F and G.

The given angles between vector HG and HF is 30° and between vector HE = 90°

Therefore, Angle between vector HE and HG = angle between HE and HF + angle between HF and HG.

∠ EHG = ∠ EHF + ∠ FHG

= 90° + 30°

= 120°

The measure of EHG = 120°

Answer 2

Answer: (Answer: 120) angle EHF = 90 degrees+30 degrees=120 angle

The bases on a softball diamond are 60ft apart. How far is it from home plate to second base

Answers

ok so I ams assuming that
from home to 1 is 60
from 1 to 2 is 60
from 2 to 3 is 60
from 3 to home is 60

so we have a squaer
from home to second base
that is a diagonal line through the square

find the distance

we see that we have 2 right triangles with legs 60 and 60

Circumference = diameter x PI

Circumference = 3.14 x 68 yards = 213.52 yards.

Area = PI x r^2

r = 1/2 the diameter = 1/2 x 68 = 34 yards.

Area = 3.14 x 34^2 = 3.14 x 1156 = 3629.84 yards^2
