PleEASSSE HELP ME WITH K AND L

Mathematics

Artist 52 [7]3 years ago

K. A quadrilateral has a total angle measure of 360. We know that two of the angles are 90, so we can subtract 180 from that. We’re left with 180. So we can make it into and equation. X+2x=180. Simplify and solve, and you get that x=60.

L. Again, a quadrilateral has a total of 360. So we can subtract the right angle from that and get 270. Put it into and equation, and you get x+2x+3x=270. Simplify and solve, and you get that x=45.

PLEASE HELPP Write the equation of the line fully simplified slope-intercept form.
Mkey [24]
The answer will be: Y = -2/5x - 4

Slope intercept form: y= Mx+b

You find the slope (M) using: rise/run formula
You find (b) by looking at the y-intercept

Remove the parentheses from the following expression and combine like terms. 3(ax + b2 - c) + 2
melisa1 [442]
To remove the parentheses, you just distribute. 
So, it will become 3ax + 3b^2 - 3c +2. I don't think there is any like term in this expression.

Consider this right triangle.<br> 21<br> 29<br> 20<br> Enter the ratio equivalent to s
AleksAgata [21]

Answer:

Part 1) sin(B)=\frac{21}{29}

Part 2) csc(A)=\frac{29}{20}

Part 3) cot(A)=\frac{21}{20}

Step-by-step explanation:

<u><em>The complete question is</em></u>

Consider this right triangle. 21 29 20 Write the ratio equivalent to: Sin B - CscA- Cot B

The picture of the question in the attached figure

Part 1) Write the ratio equivalent to: Sin B

we know that

In the right triangle ABC

sin(B)=\frac{AC}{AB} ----> by SOH (opposite side divided by the hypotenuse)

substitute the values

sin(B)=\frac{21}{29}

Part 2) Write the ratio equivalent to: Csc A

we know that

In the right triangle ABC

csc(A)=\frac{1}{sin(A)}

sin(A)=\frac{BC}{AB} -----> by SOH (opposite side divided by the hypotenuse)

substitute the values

sin(A)=\frac{20}{29}

therefore

csc(A)=\frac{29}{20}

Part 3) Write the ratio equivalent to: Cot A

we know that

In the right triangle ABC

cot(A)=\frac{1}{tan(A)}

tan(A)=\frac{BC}{AC} -----> by TOA (opposite side divided by the adjacent side)

substitute the values

tan(A)=\frac{20}{21}

therefore

cot(A)=\frac{21}{20}
