Answer:

<HKJ = 90

<FKG = 42

<FKJ = 138

<IKJ = 42

<FKH = 132

<GKI = 138

Step-by-Step :

<GKH , <HKI , and <IKJ all make up a line.  A line is 180 degrees.

90 + 48 = 138    180 - 138 = 42   <IKJ = 42

<FKG is a vertical angle to <IKJ.  Vertical angles are congruent.

<FKG = 42

<FKG and <FKJ make up a line.  A line is 180 degrees.

180 - 42 = 138    <FKJ = 138

Hope this helps.

Find the Shaded Area:<br> 10 m<br> 10 m
Greeley [361]

Answer:

100-25pi m

Step-by-step explanation:

Let us subtract the circles area from the square

<em>First, let us find the area of the square:</em>

Base x height =

10m x 10m = 100m

<em>Now, the circle:</em>

pi x radius ^2 =

pi x (10/2)^2 =

pi x 5^2=

25 pi

Therefore, the shaded area is 100-25pi m. You can also simplify it further by plugging in the 3.14... value into pi.

<em>I hope this helps! :)</em>

The boiling point of jet fuel is 329°
natka813 [3]

Since, the boiling point of jet fuel  = 329 °F

We have to convert the boiling point of jet fuel in ^\circ C.

The expression which is used to convert ^\circ F to ^\circ C is given by:

C = \frac{5}{9}(F-32)

= \frac{5}{9}(329-32)

= \frac{5}{9}(297)

= 165^\circ C

Therefore, the boiling point of jet fuel is 165 ^\circ C.

A line going through the points (-3, -10) with a slope m = 1/4.
vfiekz [6]

Step-by-step explanation:

(-3,5) and (x,y)

Slope = (y - 5)/[x - (-3)] = (y - 5)/(x + 3)

(y - 5)/(x + 3) = -1/4

y - 5 = -1/4(x + 3)

y - 5 = (-1/4)x - 3/4

y = (-1/4)x - 3/4 + 5

y = (-1/4)x + 17/4.
