Answer:
x = 40
Step-by-step explanation:
The sum of all the interior angles of a triangle is 180 degrees
So, 180-63-77 is your answer.
x = 40
1) Jane is (x - y) years old
2) Anna was (x - 3) years old 3 years ago
3) Jane will be (x - y + 5) years old in 5 years
4) The sum of their current ages is (2x - y) years
Answer:
1. you will multiply base times height:
16m * 12m = 192 sq m
2. same steps but just multiply it by two because its "twice as long"
18 cm * 6 cm = 108 * 2= 216
3. now for this one sice we are finding the base we will have to divide the 432 by 18 = 24
4. same steps like in question 1:
12 * 5 = 60
5. same steps like in question 1:
7 * 10 = 70
