Answer:
p + q = 20
Step-by-step explanation:
Given the lines intersect at (1, 1 ) then x = 1 and y = 1 make the equations true.
Consider
px = 12 with x = 1
p = 12
Consider
2x + qy with x = 1 and y = 1
2 + q = 10 ( subtract 2 from both sides )
q = 8
Hence p + q = 12 + 8 = 20
D. Multiplication Property
Answer:
W = 9 * g
Step-by-step explanation:
W/9 = g
W = 9 * g
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°
