Answer:
Half
Step-by-step explanation:
Answer: 1) 13 2) 11, 144°, 36° 3) 18, 54°, 126°
Step-by-step explanation:
For the first one to find x make the equations equivalent to each other
to make an equation.
7x - 16 = 5x + 10 // Now solve for x
add 16 to both sides
7x = 5x + 26
subract 5 from both x
2x = 26
Now divide by 2
x = 13
For the 2nd one do the same thing as last time because the equations are across from each other in parallel lines meaning they are equivalent.
12y + 12 = 15y - 21
add 21 to both sides
12y + 33 = 15y
subtract 12 from both y
33 = 3y
Now divide by 3
y = 11
Angle A is 144°
Angle B is 36°
Now solve for A ( replace y by 11 in the equation a to get an output )
12(11) +12
132 + 12 = 144°
Now to find b subtract 144 from 180
180 - 144 = 36°
For the 3rd one same thing since they are parallel.
5z - 36 = 3z
add 36 to both sides
5z = 3z + 36
now subtract 3 from both z
2z = 36
divide by 2
z = 18
Solve for C
5(18) - 36
90 - 36 = 54°
Z is 18
angle C is 54°
angle D is 126°
1 10 and 10 ones is correct
Answer: 134.9
Step-by-step explanation: Simplify the expression.
Hope this helps you out!
Since the two shapes above are congruent, meaning they are the same, you can observe that three of the four angles for the total shape are given. The angles that were given include 133, 86, and 41 degrees. However, a quadrilateral has 360 degrees, and you can find the missing angle by adding up the three given degrees and subtracting it from 360. 133+86+41=260 degrees. You can then subtract it from 360. 360-260=100. So, the degrees of the missing angle is 100 degrees.
