Answer:
first one is a and the second one is c
In order to do that we would need to see the list of potential answers.
A group of preschoolers has 30 boys and 13 girls then the ratio of boys to all children would be 30:43.
What is a ratio?
A ratio in mathematics shows how many times one number contains another. For example, if a bowl of fruit contains eight oranges and six lemons, the orange-to-lemon ratio is eight to six. Similarly, the lemon-to-orange ratio is 6:8, and the orange-to-total fruit ratio is 8:14.
A group of preschoolers has 30 boys and 13 girls.
Total children will be = 30 + 13 = 43
Ratio = number of boys/total children
= 30/43.
Hence, if A group of preschoolers has 30 boys and 13 girls then the ratio of boys to all children would be 30:43.

In this problem you only need to find the x value of one triangle. If you notice, this is a rectangle that has been cut in half by a diagonal into two equal right triangles. So both the top and bottom part are equal to 500 and both have an angle equal to 10 degrees.
Now looking at the problem, you would have to use tangent since 500 is adjacent and your X value is opposite.
Tan(10) = (X/500)
Now solve by multiplying each side by 500
X= Tan(10) 500 put this in a calculator
Answer is 88.2 degrees
Im pretty sure its 17.6 :)
