Step-by-step explanation:
3. (c) complementary since the sum of the angles is 90°
4. 5x + 95 = 180 ---> 5x = 85 or x = 17 ans (d)
5. 68 + x + 90 = 180
x + 158 = 180
x = 22
ans. (b)
So a complementary angle is going to equal 90 degrees.
The equation is : x - 10 + 4x - 10 = 90
Then, add together the matching terms : 5x - 20 = 90
Add 20 to both sides : 5x = 110
Then divide both sides by 5 : x = 22
Insert the value 22 into the first equation : (22 - 10) + (4*22 - 10) = 90
Solve : 12 + 78 = 90
Angle UVW = 12 and angle XYZ = 78
2(6d-13c) is an equivalent way to write this expression
One statement that is true when re-writing expression is that the terms cannot be combined because the variables are different.
Are there statements you can chose from, like multiple choice answers?
