Answer:
Step-by-step explanation:
1. All triangles add up to 180°, so you can make an equation like this:
2. As for which angle corresponds to ∠A, we know that ∠A is across from ∠B which is 60.8°. We know that in the other triangle, ∠Z=60.8° as well and ∠Y is right across from it. Therefore, <u>∠Y corresponds to ∠A</u>.
3. It would be useful to know the options you have for this one. I'd say they're <u>similar</u> (if that's an option).
Answer:
Each term in marks pattern is 10 more than the corresponding term in joes pattern
Step-by-step explanation:
Given
Joe
Mark
Required
Determine which option answers the question
From the question, we have that Mark and Joe have the same additional rule of increment.
This implies that, the difference of each term is the same as the difference of the starting number of both:
Since Mark started at a higher number than Joe, the difference can be said to be.
Hence:
<em>Option B answers the question</em>
Step-by-step explanation:
24% = 156
1% = 24%/24 = 156/24 = 6.5
100% = 1%×100 = 6.5×100 = 650
so, 650 students were surveyed.
Answer:
1) 25
2) 155
3) 25
4) 25
5) 19
6)
7)
CODE:
Step-by-step explanation:
1) 180 - 155 = 25
2) 155 = angle 4
3) angle 1 and 5 are equal = 25
4) angle 1 and 7 are equal = 25
5) 19
5x + 15 = 8x - 42
5x + 15 - 5x = 15
8x - 42 - 5x = 3x - 42
15 + 42 = 57
3x - 42 + 42 = 3x
57 = 3x
57 / 3 = 19
3x / 3 = x
19 = x

7)
25 + 155 + 25 + 25 + 19
