Triangle angle - sum theorem<br> what is the value of y?

dangina [55]

Answer:

y = 5

Step-by-step explanation:

All angle measures in a triangle add up to 180°.

This means that 63 + 82 + 7y = 180

<u>Solving for Y:</u>

Step 1: Combine like terms.

$(7y) + (63+82)=180$
$7y + 145 = 180$

Step 2: Subtract 145 from both sides.

$7y + 145 - 145 = 180 - 145$
$7y = 35$

Step 3: Divide both sides by 7.

$\frac{7y}{7} = \frac{35}{7}$
$y = 5$

Step 4: Check if solution is correct.

$7(5) + 63 + 82 = 180$
$35 + 63 + 82 = 180$
$98 + 82 = 180$
$180 = 180$

Therefore, y = 5.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

Please give the right answer and show work if possible

Answer:

Step-by-step explanation:

Sin 64=23/a. Let use trig identities to find other points

First, since sin and cos like are complementary angles we can use this formula

$\sin(x) = \cos(y) \: \: \: x + y = 90$

sin 64=23/a

$64 + x = 90$

$x = 26$

So cos 26=sin 64 so B is a answer

user100 [1]

Answer:

r = -9/10

Step-by-step explanation:

Given

7/10 = r - (-8/5)

Required

Solve for x

7/10 = r - (-8/5)

We start by opening the bracket

7/10 = r + (- -8/5)

7/10 = r + (8/5)

7/10 = r + 8/5

Subtract 8/5 from both sides

7/10 - 8/5 = r + 8/5 - 8/5

7/10 - 8/5 = r

Solve the fraction by taking their LCM

(7 - 16)/10 = r

-9/10 = r

Reorder the above

r = -9/10

Hence, the value of r is -9/10

Answer:

6+10+14+18+22+26

Step-by-step explanation:

Let n =1

4(1) +2 = 6

Let n = 2

4(2) +2 = 8+2 = 10

Let n =3

4(3) +2 = 12+2 = 14

Let n= 4

4*4+2 = 16+2=18

Let n=5

4*5+2 = 20+2 =22

Let n=6

4(6)+2=24+2=26

Sum these together

6+10+14+18+22+26
