linear pairs are supplementary so their sum equals 180°

(3x - 30) + (x + 76) = 180

4x + 46 = 180

4x = 134

x = 33.5

∠1: 3x - 30 = 3(33.5) - 30 = 70.5

∠2: x + 76 = (33.5) + 76 = 109.5

Answer: ∠1 = 70.5°, ∠2 = 109.5°

what is an equation of the line that is perpendicular to line y= -1/2x -2 and passes through the point (0,-4)?

LiRa [457]

Answer:

$y = 2x -4$

Step-by-step explanation:

$y = -\frac{1}{2}x - 2\ \ \ \ \ \ (0, -4)$

To find the perpendicular equation of a line,

You need the product of their gradients to be -1

$-\frac{1}{2} \times ? = -1$

Divide both sides by $-\frac{1}{2}$

? = 2

The gradient of the perpendicular line is 2

Straight line formula is in the form $y = mx + c$

$y = 2x + c$

We're nearly there, we just need to find out c.

Luckily, we're given a point $(0, -4)$

$(x, y) = (0, -4)$

$y = 2x + c$

$-4 = 2(0) + c\\-4 = 0 + c\\c = -4$

We then end up with...

$y = 2x -4$

Can someone please help me and explain how to solve them Will give 45 points

Recall that the perimeter is the sum of all the sides. So, for the first triangle, the perimeter is 4x+2+7x+7+5x-4 = 16x + 5

second triangle: x+3 + 2x-5 + x+7 (combine like terms)

Part b: Subtract the perimeter of the smaller triangle from the perimeter of the larger triangle.
