Triangle angle - sum theorem 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

Solving for Y:

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.

A shirt originally cost $36.24, but it is on sale for $30.80. What is the percentage decrease of the price of the shirt? If nece

KiRa [710]

To work out the decrease, do original amount - new amount and then take that answer and divide it by the original amount, and then multiply by 100.

So you would do:

36.24 - 30.80 = 5.44
5.44 ÷ 36.24 × 100 = 15% to the nearest percent.

Answer:

Option (4)

Step-by-step explanation:

Vertices of the triangle are X(0, -4), Y(2, -3) and Z(2, -6).

Slope of XY ( $m_{1}$ ) = $\frac{y-y'}{x-x'}$
