If measure of angle 1 = 2x+6 and measure of angle 2 = 8x+4 where angles 1 and 2 are supplementary, then how much is the actual m
nlexa [21]

Answer:

The actual measure of ∠1 = 40°

Step-by-step explanation:

We are given: ∠1 = 2x+6 and ∠2 = 8x+4

and both angles are supplementary. we need to find the actual measure of ∠1

Supplementary angles: If the angles are supplementary their sum is equal to 180°

In our case ∠1 +∠2 = 180°

2x+6+8x+4=180

Solving the equation to find x, then we can find the actual measure of ∠1

2x+6+8x+4=180\\10x+10=180\\10x=180-10\\10x=170\\x=170/10\\x=17

So, value of x = 17

Now, finding actual measure of ∠1 by putting x=17 in equation 2x+6

\angle1=2(17)+6\\\angle1=34+6\\\angle1=40

So, the actual measure of ∠1 = 40°

Can anybody find the measure of the major arc ILK?<br><br><br> click on image for full picture
Vikentia [17]

IL is a diameter, which is a straight line, which is equal to 180 degrees.

The arc of IL would be 180 degrees

You are told the arc of KL is 30 degrees.

The major arc of ILK would be 180 + 30 = 210 degrees.

1,088 if you set it up as a proportion. It would be 17/20 compared to x/1280 multiply 17 by 1280 and then divide by 20.

Given that answer please

Answer:

<BCA = 44.4°

Step-by-step explanation:

Reference angle = <BCA = C

Opposite side length = x = 7 cm

Hypotenuse = y = 10 cm

Applying trigonometric ratio, we would have:

sin(C) = \frac{7}{10}

C = sin^{-1}(\frac{7}{10})

C = 44.427004

<BCA = 44.4° (to 3 SF)
