The angle is 60° because
B is a right angle and that adds to 90°, so dividing 90 by 3 would get 30
30 x 2 = 60
and to check the answer
x = 30
A=30
B=90
C=60
this adds to 180 which is correct because the angles in a triangle add to 180° :)
Answer:
Option 4
Step-by-step explanation:
Both the quadrilaterals are similar,
ABCD ~ WXYZ
Therefore, ratio of the corresponding sides will be constant in other words ratio of the corresponding sides will be common.
Scale factor = ![\frac{AD}{WZ}](https://tex.z-dn.net/?f=%5Cfrac%7BAD%7D%7BWZ%7D)
= ![\frac{15}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B15%7D%7B6%7D)
= ![\frac{5}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B2%7D)
Therefore, option (4) will be the correct option.
again, you need to remember that EVERY straight line has the equation
y = (slope) x + (y-intercept) .
Right away, you know that this line goes through the origin ...
the equation doesn't show any y-intercept. The y-intercept is zero,
meaning that the line crosses the y-axis at the place where y=0.
That's the origin ... the place where the x- and y-axes cross.
Look at the graph they gave you. ... At first it looks like an ugly mess.
But look closer. There are only two lines there that go through the origin,
so one of those is the answer to the question.
Now let's talk about the slope of a line.
-- If the slope of a line is positive, that means it rises as it goes.
If you walk the graph from left to right, you're climbing.
-- If the slope of a line is negative, that means it falls as it goes.
If you walk the graph from left to right, you're going down-hill.
The equation they gave you is [ y = 1/2 x ].
The slope is 1/2 . That's positive.
The line on the graph slopes up. To walk it, you have to climb.
In the picture, that can only be line 'c' .
Answer:
2x+1200
Step-by-step explanation:
First remember that SUM is the addition of two things
You can rewrite the unknown "number" as (x)
You can rewrite the entire phrase as:
2(x+600)
Now use Distributive property to simplify the phrase. It should look like this:
2x+1200
You cannot simplify this anymore, giving you the final answer of 2x+1200
