Step-by-step explanation:
BCD = 180- 100 = 80
the opposite angles of a parallelogram are of equal measure
SO DAB = X = 80
The sum of all parallelogram angles = 360
360 - 160 = 200
200 equals the measure of angle ADC + ABC
ABC = ADC
200 = 2ABC
ABC = 100
ADB = DBC = 30
Y = 100 - 30 = 70
another way to find y is using the rule that says that the sum of the triangle ADB angles = 180
180 = 80 + 30 + y
y = 70
Answer:
12x+4
Step-by-step explanation:
distribute the 4 to the 3x and 1 so 3*4=12 so 12x 1*4=4

Step-by-step explanation:
Answer:
(9/5)C+32 = F
Step-by-step explanation:
1. multiply both sides by 9/5
(9/5)C = F - 32
2. Add 32 to both sides
(9/5)C + 32 = F
