The three inside angles (A,B and C) of a right angled triangle are in the ratio 7:18:11

1 answer:

6 0

This is overdetermined. Without looking at the ratio (except for the order of the sides) the actute angles in a right triangle are complementary so the answer must be:

Answer: A=35°, C=90°, B=55°

We can do it the way they like.

7+18+11 =36

so to get 180 degrees we need to scale the ratio elements by a factor of 5.

7:18:11=35:90:55

A is the smallest. We see C is indeed a right angle and B is complementary to A.

5 + 6 - (-3) - 8 + 4 -3

Okay, so -

We have one very important thing here. This little part 6 - (-3). 

Now, it's essential to remember that when we have two negatives like this, we simply draw a line straight down. It becomes a positive!

So, our question is essentially 5 + 6 + 3 - 8 + 4 - 3 = ? instead of 5 + 6 - (-3) - 8 + 4 - 3! =)

With that in mind, we simply solve left to right.

11 + 3 - 8 + 4 - 3 = ?

14 - 8 + 4 - 3 = ?

6 + 4 - 3 = ?

10 - 3 = ?

7 is our final answer! =)
