The sum of the angle measured in a triangle is 180°.two angle of a triangle measures 20° and 50°.what did is the measure of the third angle

110 Degrees

Step-by-step explanation:

The sum is when different numbers are added.

When all angles are added it adds up to 180 Degrees for any triangle.

Triangles have three sides and two are given as 50 Degrees and 20 Degrees.

There is one angle remaining.

50 Degrees + 20 Degrees = 70 Degrees

Therefore, the last angle must be 110 Degrees. (180-70)

third choice down

step-by-step explanation:

the first inequality is based on the number of adults and campers, and the second inequality is based on the cost of feeding both the adult and the camper.

we know that there is room for 525 people max.   it's ok to have less than 525, but it's not ok to have more than 525, so the inequality is less than or equal to.   the number combination of adults (x) and campers (y) cannot exceed this 525 max.   therefore:

x + y ≤ 525

now we talk about cost.   it costs $9 to feed one adult, so depending upon the number of adults you have (x) depends upon how much it will cost to feed that number of adults.   same with the campers, who cost $5 to feed.   the adults can be represented by 9x and the campers can be represented by 5y.   since the budget cannot exceed 1,200, the second inequality is:

9x + 5y ≤ 1200

this "question" looks more like a project is there any other info you can give me about this. it could be too complex for someone else to do on this website
