Can someone answer this question please please help me I really need it if it’s correct I will mark you brainliest .

Step 1) Divide the figure into separate shapes

Large rectangle: 8 x 9

Medium rectangle: 4 x 6

Quarter circle: r = 3

Step 2) Find the area of each shape

Large rectangle: A = 8 x 9 = 72

Medium rectangle: A = 4 x 6 = 24

Quarter circle: A = 1/4 x 3.14 x 3^2 = 7.065 + 3 = 10.065

Step 3) Add the areas together

A = 72 + 24 + 10.065 = 106.065 square millimeters (may need to round to 106.07, but rounding not given in the problem)

Hope this helps! :)

Find the value of x using trig please .....
iren [92.7K]

Answer:

8.090169944 or rounded 8.1

Step-by-step explanation:

Use SOH CAH TOA

Look at x and where it is and what you have.

First thing is to get an angle to use, 36, then to set up your equation.

___(36)=___

Figure out what you have.

You have the hypotonouse, 10, and need the adjacent,x, so you use the equation that involves H for hypotonouse and A for adjacent.

You set up your equation using COS, as you are using CAH.

Cos(36)=x/10

X is over ten sure to CAH C-cos A-adjacent and H-hypotonouse

Switch it around to make it equal to x

10*Cos(36)=x

You input it into your calculator. [10] [COS] [36] [ENTER] and you get the answer.

Round however is needed.

What does b represent in the equation of a line in the form y=mc+b
Olin [163]

Do you mean y = mx + b instead of y = mc + b? In that case:

b in y = mx + b format is the y-intercept, as this kind of equation is called slope-intercept form.
