None because a triangle has to equal 180 degrees and the measurements you have equal 200 degrees. So no triangles can be constructed with those measurements

Answer:  3, 5, 7

Step-by-step explanation:

There is a "trick" to determine divisibility by 3: if the sum of the digits is divisible by 3, the number is divisible by 3.

3 + 1 + 5 = 9 which is a multiple of 3, so 315 is divisible by 3.

It works for 9 also. since the sum of the digits is 9, 315 is divisible by 9.

Divisibility by 5: any number that has the units digit 5 or 0 is divisible by 5.

For 7, I just tried it  315÷7= 45

Only even numbers are divisible by 2.

If a 3-digit number is divisible by 11, the middle digit will be the sum of the first and last digits.   (That is not the case for 315)  But 385 is divisible by 11, also 495, 253, and many others you can try for fun.

A washer and dryer cost $869 combined. The washer cost $81 less than the dryer. What is the cost of the dryer?
marysya [2.9K]
W+d=869
w=d-81
plug in
(d-81)+d=869
2d-81=869
+81 both sides
2d=950
÷2 both sides
d=475
dryer cost $475

let's check w=475-81
w=394
475+394=869
869=869
the solution is true :)
