Answer:
1) ABCD is a rhombus
2) All sides of a rhombus are equal.
4) SSS
5) CPCTC
Total time = upstream time + downstream time
he rowed the same distance both ways.
upstream time = D/4
downstream time = D/6
total time = D/4 + D/6 = 3D/12 + 2D/12 = 5D/12 = 3 hours
D = 3*12/5 = 36/5 or 7.2 miles
where D is the one-way distance. The total distance he rowed is 2*D = 72/5 or 14.4 miles
Answer:
m<1 = 51
m<2 = 61
m<3 = 29
Step-by-step explanation:
three angles of a triangle = 180
so knowing that add 68 + 61 to get 129
now subtract cause the last angle will = 180-129 = 51
for angle two is 61 cause their congruent
now we have one angle = 90 and another 61
add them 90+61= 151
now subtract 180-151 = 29
Answer:
8
Step-by-step explanation:
According to Euclidean theorem
m^2 = 4×16
m^2 = 64
m = 8
Answer:
d) -2
Step-by-step explanation:
(-1 - 19)/(16 - 6)
-20/10 = -2
