Answer:
An acute angle ("acute" meaning "small") is an angle smaller than a right angle. The range of an acute angle is between 0 and 90 degrees.
An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles. Since a triangle's angles must sum to 180° in Euclidean geometry, no Euclidean triangle can have more than one obtuse angle.
Protractor: an instrument for measuring angles, typically in the form of a flat semicircle marked with degrees along the curved edge.
Degrees: a unit of measurement of angles, one three-hundred-and-sixtieth of the circumference of a circle.
Right Angel: an angle of 90°, as in a corner of a square or at the intersection of two perpendicular straight lines.
Straight Angle: an angle of 180°.

Answer:
a < -12
Step-by-step explanation:
Isolate the variable, a. Treat the < as a equal sign, what you do to one side, you do to the other. Subtract 2 from both sides:
a + 2 < -10
a + 2 (-2) < -10 (-2)
Simplify:
a < -10 - 2
a < -12
a < -12 is your answer.

Answer:
The shape is a kite and x=26
Step-by-step explanation:
The shape is a kite because the two adjacent sides at the right match and the two sides on the left match
To find x:
125+125=250
360-250=110
(3x-11)+(2x-9)=110
Combine like terms: 5x-20=110
Add 20 to both sides: 5x-20+20=110+20
5x=130
Divide both sides by 5: 5x/5=130/5
x=26
Answer:
1.5$
Step-by-step explanation:
10 cupcakes =15$
so, 1 cupcake = 15/10
i.e. 1.5
.: 1cupcake cost = 1.5$
