Answer:
a) 77.13
b) 179.97
Step-by-step explanation:
3x + 3x + 4x + 5x + 6x + 7x = (6 - 2) × 180
28x = 720
x = 720/28
x ≅ 25.71
3 × 25.71 = 77.13 = smallest angle
7 × 25.71 = 179.97 = largest angle
I think the answer should be 12 but......
Answer:
a = 0
Step-by-step explanation:
3(4a+7)=5(2a+4)+1 Distribute 3 through the parentheses
- > 12a + 21 = 5(2a + 4) +1
5(2a + 4) +1 --> 10a + 20 + 1
12a + 21 = 10a + 20 + 1 --> 12a + 21 = 10a + 21 --> 12a = 10a
12a - 10a = 0 --> 2a = 0
Divide both sides of the equation by 2 --> a = 0
11/10 is closer to 1.
To solve for this, give them common denominators. Lets make it 80 for this one.
To get 80, you multiply 8 by 10, so you have to do the same to the number on top. This gives you 70/80.
To get 80 for the second fraction, you multiply by 8 and get 88/80.
Now lets take the numbers on top and subtract them from 80.
88 - 80 = 8
80 - 70 = 10
8 is less than 10, and so 11/10 is closer.
Answer:
92
Step-by-step explanation:
The parallelogram is divided into two triangles. Remember, angles in a triangle add up to 180 degrees. That being said, take the sum of the numbers given in triangle ABC and subtract it from 180.
60 + 28 = 88
180 - 88 = 92 (this is the measure of angle B)
Angles D and B are congruent, which means they are the same.
Since Angle B is 92 degrees, then D is 92 degrees also.
