Answer:
Step-by-step explanation:
∠2 is a right angle, so ∠3 is complementary to the 39° angle shown. It is ...
∠3 = 90° -39° = 51°
ΔDAB is isosceles, so ∠DBA ≅ ∠3 and ∠1 ≅ 39°.
_____
If you're starting completely from scratch, you might go to the trouble to show ΔABC ≅ ΔADC, hence AC is a bisector of angles A and C. If X is where the diagonals cross, then you can show ΔABX ≅ ΔADX and ∠2 is 90°.
I prefer to start with the fact that the diagonals of a (symmetrical) kite cross at right angles. That makes all the triangles right triangles, so the angles are easily found, given any one of them. (Acute angles of a right triangle are complementary.) Of course, the triangles on one side of the line of symmetry (AC) are congruent to those on the other side.
Answer:
20 pounds
Step-by-step explanation:
If the model statue weighs 4 pounds and scale is 1:4, then 4x5=20.
Find the Greatest Common Factor (GCF)
GCF = 10
Factor out the GCF (So, write the GCF first, and then in parenthesis, divide each term by the GCF.)
10(60y/10 - 90/10 + -20x/10)
Simplify each term in parenthesis
<u>10(6y - 9 - 2x) </u>
