We know two sides of the triangles are congruent to each other
MD = MT
and MA = MU
We also know that <DMA = < TMU
Two sides and the included angle
We can use SAS to show that the triangles are congruent

Answer:
1) 4-(-6) = 10
2) -10.3-(-7.79)= -2.51
3) -4+6 1/2= 2 1/2
4) -10.2+4.38= 5.82
5)
Step-by-step explanation:
1) A double - equals positive so change to
4+6=10
2) adding positive to negative makes it less negative
3) just change positions -4 from 6 1/2
4) makes it less negative
5) sorry I hat fractions can't do it
Answer:
a₁ = 38
Step-by-step explanation:
Given AP, where:
=============
<h3>Solution</h3>
aₙ = a₁ + (n-1)d
- a₈ = a₁ + 7d = a₁ + 7*(-2) = a₁ - 14
- a₁₂ = a₁ + 11d = a₁ + 11*(-2) = a₁ - 22
8a₈ = 12a₁₂
- 8(a₁ - 14) = 12(a₁ - 22)
- 2(a₁ - 14) = 3(a₁ - 22)
- 2a₁ - 28 = 3a₁ - 66
- 3a₁ - 2a₁ = -28 + 66
- a₁ = 38
