Explanation:
Triangle ABC is isosceles because AC = BC.
The angles opposite these congruent sides are angle ABC and angle BAC. These are the base angles.
For any isosceles triangle, the base angles are congruent.
Angle BAC = 69 degrees is given. So angle ABC = 69 as well.
-------------------
The missing angle must add to the two other angles so that all three angles in a triangle add to 180
(angle ABC) + (angle BAC) + (angle BCA) = 180
69 + 69 + (angle BCA) = 180
138 + (angle BCA) = 180
angle BCA = 180-138
angle BCA = 42
Angle DCE is congruent to angle BCA because they are vertical angles.
Triangle DCE is a right triangle. The missing angle is 90-(angle BCA) = 90-42 = 48
angle EDC = 48 degrees
Answer:
48
Step-by-step explanation:
THE ANSWER IS 48 SORRY I CAN SEE IT NOW SORRY
$8x + $12y = $120
x = amount of juice
y = amount of pizza
$120 = his total money
√y-2a/-b = x
Answer: 30
A LCD, or least common denominator, is the lowest common multiple of both denominators.
Multiples of 5: 0, 5, 10, 15, 20, 25, <u>30</u>, 35, 40, ...
Multiples of 6: 0, 6, 12, 18, 24, <u>30</u>, 36, 42, 48, ...
We can see the LCD of 3/5 and 5/6 is:
30
