Answer:
4 : 34
5 : 102
Step-by-step explanation:
This problem can be solved by using concept of co-interior angles.
co interior angles are those angles which lie on the same of parallel lines when the parallel lines are cut by transversal.
sum of co interior angles is 180 degrees.
In the problem 4 and 5 then angle given and missing angles are co-interior angles.
Problem 4
146 + ? = 180
? = 180 -146 = 34
Thus missing angle in problem 4 is 34 degrees
Problem 5
78 + ? = 180
? = 180 -78 = 102
Thus missing angle in problem 5 is 102 degrees
Answer: The number of kittens= 500.
Step-by-step explanation:
Given, A random sample of cats at the SPCA shows that 25 out of the 40 cats are kittens.
i.e. ratio of kitten to cats =
We assume that , the ratio will remains same.
Let x be the number of kitten out of 800 , then we have
Hence, the number of kittens out of 800 cats= 500.
The area of the square can be found by...
0.75 • 0.75 = .5625
The area of one triangle can be found by...
1/2 • 0.8 • 0.75 = .3
In order to find the total surface area of the figure, you must...
.5625 + 4(.3) = 1.7625
So the answer is D
