Which is a possible measure of DCA in the triangle below?
1 answer:
Answer:
70°
Step-by-step explanation:
The total angle in a triangle is 180°. The total angle in a straight line is 180°. From the image attached, the ∠DCA must be greater than 45° because ∠BCA is greater than 90°. This means that ∠DCA is not 36° or 38° or 40° but it is 70°.
Therefore ∠DCA = 70°.
∠BCA + ∠DCA = 180° (angle on a straight line)
∠BCA = 180 - ∠DCA = 180 - 70 = 110°
∠BCA + ∠BAC + 40 = 180° (angle in a triangle)
∠BAC = 180 - 110 - 40 = 30°

Answer:
Product of -2 and 5 is -2 times 5, or 5 times -2 (5 * -2).
You can think of this as 5 lots of -2.
If each (-) is a negative,
-2 = (-)(-)
5* -2 =
(-)(-) (-)(-) (-)(-)
(-)(-) (-)(-)
= -10
