Answer:
Yes, both triangles are congruent to each other by SIDE ANGLE SIDE property of congruence.
Step-by-step explanation:
Two triangles are said to be congruent if and only if they have same corresponding angles and sides.
Now, here
Side 1 = Side 2 (given)
Side 3 = Side 4 (given)
Central angle of triangle 1 = Central angle of triangle 2 (Vertically Opposite)
Hence, by the rule of SIDE ANGLE SIDE (SAS) rule of congruence ,
Triangle 1 ≅ Triangle 2

Answer:
63.75
Step-by-step explanation:
this is a geometric progression with a common ratio of -1/2
the formula for the sum of first n numbers is
Sn = (a1(1-r^n)) / 1 - r
so S8 = (32*(1 - 1/2^8)) / (1 - 1/2)
32*(255/256) / 0.5
Sn= 255 / 4 = 63.75
The correct choice is the first one
It’s 315 hours because 60 divided by 4 equals 15 then multiply 15 and 3 equals 45 then multiply 45 and 7
