Answer:
70° and 110°
Step-by-step explanation:
The sum of angles is 180°; their difference is 40°. So, the larger is ...
(180° +40°)/2 = 110°
The smaller is 180° -110° = 70°
The two angles are 70° and 110°.
_____
Above, we have "cut to the chase." If you let the larger be 'a' and 's' and 'd' represent the sum and difference, you have ...
a + (a-d) = s . . . . the sum of the larger and smaller angles
2a = s+d . . . . . . add d
a = (s+d)/2 . . . . the relation we used.
Answer:
A triangular scarf is an isosceles right triangle.
Step-by-step explanation:
Given: A scarf is a triangle with two perpendicular sides that are the same length.
We have to name which two terms describe a triangular scarf.
Isosceles triangle is a triangle with length of two of its sides equal.
Right angled triangle is a triangle in which one angle is a right angle.
Given :
The two sides of scarf are perpendicular to each other.
Thus, the angle formed between them is 90°. Hence, right angled triangle.
Also, length of two sides are same, Hence isosceles triangle.
Thus,a triangular scarf is an isosceles right triangle.
Answer:
I would say A
Step-by-step explanation:
I'm saying its a because normally the Volume formula would be
V= h/3 (pi) r^2
so if it is doubled it should be
V=2/3 (pi) r^2
Answer:
The expression of amount of gas is 
Step-by-step explanation:
Given:
25 gallons of gas were pumped into two different size tanks.
Now, to express the amount of gas pumped into the smaller tank in terms of the amount 
pumped into the larger tank.
Let the amount of gas pumped into smaller tank be 
And according to question, the amount of gas pumped into larger tank is .
Total amount of gas pumped into both size tanks = 25 gallons.
So, to express the amount of gas pumped into the smaller tank in terms of the amount pumped into the larger tank:
<em>Subtracting both sides by </em><em> we get:</em>
Therefore, the expression of amount of gas is
The answer to #2 is D, 0.
