Answer: x=80°
Explanation:
To find the exterior angle x we first need to find the last corner angle (a) of the triangle. The angles of triangles add up to 180° so we can use the formula: 25+55+a=180
Solving formula:
25+55+a=180
80+a=180
(Subtract 80 from both sides)
a=100°
Now that we know a=100 we can find the exterior angle. a+x=180 because the angles are on a straight line which equals 180°
a+x=180
100+x=180
(Subtract 100 from both sides)
x=80°

Answer:
It is A
Step-by-step explanation:
The guy below is wrong because I got a 100 on the quiz on Edge.
Answer:
4/12
Step-by-step explanation:
1/6 - 2/12
2/6 = 4/12
Answer:
(8x-1) (x-1)
Step-by-step explanation:
8x² - 9x + 1
(8x - ) (x - )
We know it is minus because we have -9x
We have +1 so both have to be -
To fill in the blanks we put 1
The only combination is 1*1 =1
(8x-1) (x-1)
Lets check
8x^2 -x -8x +1
(8x^2 -9x+1
Answer:
Step-by-step explanation:
take 45 degree as reference angle
using sin rule
sin 45=opposite/hypotenuse
1=x/16
x=16/
x=8
