Answer:
(a) no
(b) no
Step-by-step explanation:
The two questions are asking essentially the same thing. There is nothing that indicates DC ≅ DB or that AC ≅ AB. One (both) of these conditions is (are) required for ΔBAC to be isosceles, so that AD is both a perpendicular bisector of BC and a bisector of angle BAC.
There is not enough information to answer either question affirmatively.
Answer:
A
Step-by-step explanation:
You're correct. The Y intercept is the B. And 3 the slope.
.0562 is the smallest number
Answer:
∠ABC= 180° -21° -37° (∠ sum of triangle ABC)
∠ABC= 122°
Using sine rule,
AB= 200(sin21°)/sin 122°
AB= 84.5 units (3 s.f.)
BC= 200(sin37°)/ sin122°
BC= 142 units (3 s.f.)
