Answer:

Step-by-step explanation:

If EG is a diameter, then arc EFG is a semicircle and its measure is 180. Arc FG then is 180 - 124 = 56. Since angle FEG is an inscribed angle and the arc it cuts off is arc FG, then the measure of the inscribed angle is half the measure of the arc it cuts off...so angle FEG is 28 degrees. Keep that in mind; we'll need it in a sec.

If HE is tangent to the circle at E, then angle HEG is a 90 degree angle. Adding that to angle FEG will give you angle FEH. Angle FEH = 90 + 28 = 118

Find the missing side and angles.
sweet [91]

Answer:

Step-by-step explanation:

This is an equilateral triangle.

The altitude bisects the 60 degree angle, so a=30

b=60 since its an interior angle of the isosceles triangle.

e = 4 since the two triangles formed by the altitude are congruent.

c = 8 since the side length is 4 + 4 = .

f = 4sqrt3 by the properties of 30 60 90 triangles.

Please help me guys it is due today there is a second part i will do anything so ANSWER PLS!!! ASAP
Fantom [35]

Answer:

see below

Step-by-step explanation:

To find the combined length of Pine and Elm and the lengths together

Pine +Elm

We are estimating by rounding to the nearest whole number

Pine is 2.7 so it rounds to 3 because we look at the .7 and since .7 is greater than .5 it rounds the 2 to 3

Elm is 8.9  so it rounds to 9 because we look at the .9 and since .9 is greater than .5 it rounds the 8 to 9

2.7 + 8.9 rounds to 3+9 = 12

12 is reasonable because the actual answer is 2.7+8.9 = 11.6 which rounds to 12

Does x+y=1 have an x-intercept of (1,0) and y intercept of (0,1)?
aivan3 [116]

Answer:

Yes

Step-by-step explanation:

To find the y intercept of this formula, you first need to convert it into slope intercept form.

x+y=1

y=-x+1

Here, the slope is negative 1 and the y intercept is (0,1). If you imagine the line with a slope of negative 1, it will indeed cross the x axis at (1,0). Hope this helps!

Find the slope y - 2 = -3 (x+1) <br><br> (show steps!!)
Vsevolod [243]

y - 2 = -3 (x+1)

point slope form

y-y1 = m(x-x1)

looking at the above equation

the slope is -3
