Answer:
Your answers are 1,4,5
Step-by-step explanation:
Triangles add up to 180 degrees, so all you have to do is add the degrees together.
86+53+41 = 180
47+84+56 = 187
70+22+68 = 160
54+97+29 = 180
33+90+57 = 180
Actually Welcome to the concept of Angle sum property of a triangle.
To form a triangle, all angles must sum exactly to 180°.
So the correct options are :-
1.) 86°, 53°, 41°
4.) 54°, 97° , 29°
5.) 33° , 90° , 57°
54.25
n = # of days
45 = 2.5n + 2n
45 = 4.5n
n = 10
He can paint 45 structures in 10 days
Answer: y=3/4x+3/2
Let's solve for y.
3x−4y+6=0
Step 1: Add -3x to both sides.
3x−4y+6+−3x=0+−3x
−4y+6=−3x
Step 2: Add -6 to both sides.
−4y+6+−6=−3x+−6
−4y=−3x−6
Step 3: Divide both sides by -4.
−4y/−4= −3x−6/−4
y=3/4x+3/2
13.5
