Answer:r
Step-by-step explanation:
let x and y this numbers : x +y = -103 and x = y +59
so : y+59 +y = -103
2y +59 = -103
2y +59-59 = -103-59
2y = -162
y = -162/2
y = -81 but x = y +59
so : x = -81+59
x = -22
Answer:
is the 23% going into the 42.5
Answer:
x = 4
Step-by-step explanation:
We know that M is the mid-point of AB. So,
AM = BM ( A mid point divides a line segment into 2 equal parts. )
Also it's given that length of AM is 20 & length of BM is 3x + 8.
But as AM = BM ,
Answer: X intercept (-2,0) Y intercept (0,-7)
Step-by-step explanation:
The theorem is used to prove △ABC≅△DEC is Side-Angle-Side(SAS) theorem
The two triangles are
△ABC and △DEC
Here we have to prove that the △ABC and △DEC are congruent
It is given that
The length of AC = The length of CD
The angle ACB = The angle ECD
The point C is the midpoint of EB
Therefore,
The length of BC = The length of EC
Therefore, the two sides and one angle of triangle ABC is equal to the two sides and one angle of triangle DEC, so the both triangles are congruent by SAS rule
Hence, the theorem is used to prove △ABC≅△DEC is Side-Angle-Side(SAS) theorem.
