Try describing the amount of numbers in the square u know like "shade covers 2/4 of the square''
Answer:
1) 180 degrees; straight angle
2) (5x-18)+(4x+45)=108
3) x=17
4) 90 degrees; right angle
5) (3x+6)+(5x+4)=90
6)x=10
Step-by-step explanation:
We hates fractions
times everybody by 6x
6=x²-5x
minus 6 both sides
0=x²-5x-6
factor
what 2 numbers multiply toget -6 and add to get -5
-6 and 1
0=(x-6)(x+1)
set to zero
x-6=0
x=6
x+1=0
x=-1
x=6 or -1
The postulate that prove that the two triangles in your problem is congruent is SAS or Side Angle Side postulate. This postulate is use when the given of an equation are only 2 side and an angle and also it gives the answer or the side on which the angle is projected. By means of that you can tell or figure out that the two triangle is congruent. So the answer is letter B. SAS
