Answer: x=49
Step by step explanation: to find one of the sides just subtract 35 from 60, then you get 35/25=x/35, which is 25x=1225, the last step is to divide both sides by 25 and you get the final result of 49
Add 2 to both sides and x will equal 2
Answer:
i'm pretty sure that it is 27 due to vertical angle theorem
let me know if its right :)
Step-by-step explanation:
Answer:
6, 11, 16, 21
Step-by-step explanation:
To obtain the first 4 terms add the common difference 5 to the previous term, that is
a₁ = 6
a₂ = a₁ + 5 = 6 + 5 = 11
a₃ = a₂ + 5 = 11 + 5 = 16
a₄ = a₃ + 5 = 16 + 5 = 21
Since angles A and C are equivalent, then angles B and D must also be equivalent. So if
angle B = angle D then...
7x + 15 = 8x
Now we just solve for x
7x + 15 = 8x
15 = 8x - 7x
15 = x
We Can check to see if it is correct by substituting 15 in for x in the equation..
7x + 15 = 8x
7 (15)+15 = 8 (15)
105 +15 = 120
120 = 120
It checks! angles B and D = 120 degrees
