Answer:
22 degrees, 1. 2 degrees, 2. 14 degrees, 3. 14 degrees, 4.30 degrees
Step-by-step explanation:
To get the congruent angles we shall use the sine rule since we have the length of at least 1 side and the values of the angles.
Base length=12 inches
Base angles=50°
Third angle=180-(100)=80°
thus applying the sine rule we shall have:
a/sin A=b/sin B=c/sin C
thus we can get the congruent side as follows:
a/sin 50= 12/sin 80
a=(12 sin 50)/sin 80
a=9.334 inches
since the sides are congruent then the other congruent side will have a length of 9.334 inches
Answer:
3. 18 meters.
4. A= 6. 25cm^2 and P= 10 cm
5. 16 feet and 3 feet.
Step-by-step explanation:
3. base= 2 (A/h)
2 (72/8) = 18
4. A= side^2
2.5^2 = 6.25
P= 4 sides
2.5 x 4= 10
5. 16x3= 48
Step-by-step explanation:
Find equation
y - y1 = m(x - x1)
y + 9 = -5(x - 2)
y = -5x + 10 - 9
y = -5x + 1 → Equaton
