Step-by-step explanation:
The choices are not given but the graph looks like the above picture.
Given:
Measure of arc FJ = 84°
Measure of arc GH = 76°
To find:
The measure of angle HKJ.
Solution:
The image of the question is attached below.
Angles inside the circle theorem:
If two chords intersect inside a circle, then the measure of each angle is one half the sum of the measures of the intercepted arc and its vertical arc.
Sum of the adjacent angles in a straight line is 180°.
⇒ m∠GKH + m∠HKJ = 180°
⇒ 80° + m∠HKJ = 180°
Subtract 80° from both sides.
⇒ 80° + m∠HKJ - 80° = 180° - 80°
⇒ m∠HKJ = 100°
The measure of ∠HKJ is 100°.
Answer:
24 shamrocks had three leaves.
Step-by-step explanation:
We have been given that Parker was picking shamrocks he picked a total of 40 shamrocks two fifths of the shamrocks had four leaves. The rest of the shamrocks had three leaves.
First of all, we will find two fifths of 40 to find number of shamrocks with four leaves.
Now, we will subtract number of shamrocks with 4 leaves from total number of shamrocks to find number of shamrocks with 3 leaves as:
Therefore, 24 shamrocks had three leaves.
