You can't remove a variable but you can separate the variable from the rest of the equation. If you are adding for example 64+x=88 you would subtract the 64 from 88. You will get the value of x. For anything else, you would do the opposite of whatever you are doing. Multiply if you are dividing, add if you are subtracting and hence forth. I hope this helped.
The answer would be (-1, -1) on a coordinate grid.
(-6+4)/2=x
(-2)/2=x
-1=x
(5+-7)/2=y
(-2)/2=y
-1=y
Sin 45° = opposite side length/hypotenuse length
Cross Multiply and you get
opposite side length = hypotenuse length x Sin 45°
Now all You need to know is the hypotenuse length. It will help you find the opposite side length.
HOPE THIS WILL HELP.
Answer:
- a° = 70°
- b° = 78°
- c° = 139°
- d° = 17°
- e° = 123°
- f° = 69.5°
Step-by-step explanation:
You need to take advantage of what you have learned about inscribed angles. Each inscribe angle is half the measure of the arc it intercepts. Of course, the sum of all arcs around a circle is 360°.
Putting these facts together, you can quickly conclude that opposite angles of an inscribed quadrilateral are supplementary:
a = 180 -110 = 70
b = 180 -102 = 78
The arc (c+81) is opposite the inscribed angle marked 110, so we have ...
c + 81 = 2(110)
c = 220 -81 = 139
The arc (c+d) is intercepted by the angle marked b, so we have ...
139 +d = 2(78)
d = 156 -139 = 17
The arc (e+81) is intercepted by the inscribed angle marked 102, so ...
e +81 = 2(102)
e = 204 -81 = 123
The inscribed angle f intercepts arc c, so is half its measure.
f = 139/2 = 69.5
