100 more than 146 is 246
add 100 to 146 and it becomes 246
Answer: 80
Step-by-step explanation:
7824/10 = 782.4
The value represented by 8 is 80 or 8 tens.
Answer: choice B, 40.5 degrees
The triangle is isosceles based on the fact that AC = BC (the tick marks are the same). The angles opposite the congruent sides are also congruent
angle A = angle B = x for some unknown number x
The three angles A,B,C add to 180, so,
A+B+C = 180
x+x+99 = 180
2x+99 = 180
2x = 180-99
2x = 81
x = 81/2
x = 40.5
So angle A and angle B are both 40.5 degrees
Check:
A+B+C = 180
40.5+40.5+99 = 180
180 = 180 answer is confirmed
==============================
Edit
The sides with the two tick marks are the same length, so 7x-4 is the same as length as 31
7x-4 = 31
7x = 31+4
7x = 35
x = 35/7
x = 5
Answer is choice B) 5

Answer:
x = 135 degrees
Step-by-step explanation:
For any simple n-gon, the sum of the interior angles is 180(n − 2) degrees. (n is the number of vertices)
180(6-2)=180(4)=720
the shape already has 2 90-degree angles, subtract both of those from total interior angle sum
720-90-90=540
the 4 angles left must make up 540 degrees
540/4=135
x=135 degrees
