Answer:
A = 140
Step-by-step explanation:
Area of a triangle:
A = 1/2bh
Given:
b = 20
h = 14
Work:
A = 1/2bh
A = 1/2(20)(14)
A = 10(14)
A = 140
Answer:
d
Step-by-step explanation:
E is ththe answer
the first equation should be T + C = 118 and the second equation should be C + 26 = T
none of these equations are correct
A solution can be found using substitution by substituting the ordered pair into both of the original equations.
Answer is A i hope it helps
In the half-angle formula for sine and cosine, notice that a plus/minus sign appears in front of each radical (square root). Whether your answer is positive or negative depends on which quadrant the new angle (the half angle) is in
