What is the answer?​
zepelin [54]

Answer:

<em>x = 110° ; y = 49°</em>

Step-by-step explanation:

m∠ABD = m∠ADB = 35° ⇒ <em>x</em> = 180° - 2 × 35° = <em>110°</em>  

m∠CDB = m∠CBD = 2y ⇒ <em>y</em> = (180° - 82°) ÷ 2 = <em>49°</em>

1. Point S lies in plane H.
irinina [24]

Points, lines, planes are all undefined terms of geometry

<h3>Point S line in plane H</h3>

To do this, we draw a plane H (represented by a rectangle), and then add a point on the rectangle

<h3>Plane I contains line EL</h3>

To do this, we draw a plane I (represented by a rectangle), and then draw a line on the rectangle

<h3>Plane A, B and C are collinear</h3>

This means that a line passes through points A, B and C or in other words, points A, B and C are on the same line

<h3>Lines x and y intersect at a point M</h3>

This means that point M is a common point on lines x and y or in other words, point M lies on both lines

<h3>Plane A and R intersect at line JI</h3>

This means that line JI lies on both planes

What is the solution to the system of equations?
Sever21 [200]

Answer:

(-2,\frac{5}{3})

Step-by-step explanation:

Given:

The system of equations given are:

y=\frac{2}{3}x+3\\x=-2

Plug in x=-2 in the first equation and solve for y.

y=\frac{2}{3}(-2)+3\\y=\frac{-4}{3}+3\\y=\frac{-4}{3}+\frac{9}{3}\\y=\frac{-4+9}{3}=\frac{5}{3}

Therefore, the solution is (x,y)=(-2,\frac{5}{3})
