Answer:
A= 649.71
Step-by-step explanation:
A=2(1+2)a2
=2·(1+2)·11.62
≈649.71315
Answer:
<em>EF = 5 units</em>
Step-by-step explanation:
If ΔABC and ΔDFE are congruent, then
AB = DF
BC = FE
CA = ED
and
angles A and D are congruent
angles B and F are congruent
angles C and E are congruent
If sinα=cosß it means that ß=90-α. This also means that α+ß=90 so we can say:
4k-22+6k-13=90
10k-35=90
10k=125
k=12.5°
...
The above identity comes up a lot, and is one worth committing to memory for sure.
sinα=cos(90-α) or vice versa cosα=sin(90-α)

a y-intercept is any point that has an x-value of 0. for example, the ordered pairs (0,6) and (0,-4) would both be considered y-intercepts since any point with an x-value of 0 overlaps with the y-axis.
