Actually Welcome to the concept of Equilateral triangles.
Since, from the name itself, equilateral triangles have all sides and angles equal.
Hence the correct answer is
==> D. All sides are the same length.
For 12x^4 + 18x^2, each term has x^2 and then look at 12 and 18.
Both 12 and 18 are divisible by 6 so the greatest common factor would be 6X^2<span />
P = 2 + 3 + 2 + 5 , where P is the perimeter;
P = 12 cm;
The correct answer is B.
Answer:
80°
Step-by-step explanation:
Plot two lines: line passing through the points R, S and U and line passing through three points V, S and T (see attached diagram).
These line intersect at point S and form four angles: RSV, VSU, UST and TSR.
Angles VSU and RST are vertical angles, angles RSV and UST are vertical angles. Vertical angles are congruent, so
m∠VSU = m∠RST = 100°
m∠RSV = m∠UST
Angles RSV and VSU are supplementary angles (add up to 180°). Som
m∠RSV = 180° - m∠VSU =180° - 100° = 80°
Angle RSV is angle VSR (we can read from the right to the left or from the left to the right angle's name)
Answer:
0.33
Step-by-step explanation:
An hour is 60 minutes. 20 goes into 60 three times, so it is 1/3 of an hour or 0.333333333333, etc. As a percent, 20 minutes is 33.33%. Converted to a decimal, it is 0.33 or 1/3 of an hour
