How to find the angle of triangle only knowing the right angle?

There are many different ways to figure this out but may I ask you one question....do you know whether the two legs are congruent or just the right angle?

Can someone please explain to me the difference between SAS and SSS in Geometry when dealing with triangle proofs?

ANTONII [103]

Hello from MrBillDoesMath!

Answer: SAS = side - angle -side congruence

SSS = side - side - side congruence

Discussion :

In Plane Geometry, identical triangles are said to be "congruent". There are several ways, depending upon the information you have, to prove 2 triangles are congruent.

In one approach ("SSS") if you can show that 2 triangles have identical side lengths, then the triangles are congruent. (A triangle has 3 sides, hence "SSS" -- 3 S's; 3 sides, get it?)

In another approach ("SAS") if you can show that 2 sides, and the angle included between those sides, in one triangle are identical to the sides and included angle in another triangle, then the triangles are congruent

It's easier to understand this with a picture or diagram than in words. Please review the SSS, SAS picture in your textbook

Solve, be sure to show each step under the original problem for any credit. 1 =k/12 +5

Naya [18.7K]

K = -48

1. subtract 5 from both sides
-4 = k/12

2. multiply 12 from both sides to get k alone
-48 = k

Rita's company reimburses her expenses on food, lodging, and conveyance during business trips. The company pays $55 a day for fo

MArishka [77]

"The company pays $55 a day for food and lodging and $0.45 for each mile traveled" means that if she travels m miles and is on a trip for x days then Rita will receive:

55x + 0.45m dollars.

Rita drove 300 miles, means that m=300. Thus 55x + 0.45m becomes 

 $55x+0.45m=55x+0.45 \cdot 300=55x+135$ (dollars.)

She was reimbursed $2,335 means that $55x+135=2,335$ .

Part A: $55x+135=2,335$ .

Part B:

We are given the equation 55x+135=2,335. Subtracting 135 from both sides we have:

55x=2,335-135=2,200.

Dividing both sides by 55, we get: x=2,200/55=40.

Part C: since x represents the number of days Rita spend on this trip, and x=40, then Rita spent 40 days on this trip.
