Answer:
69°, 69°, and 42°
Step-by-step explanation:
Isosceles triangles have three angles -- one vertex angle and two base angles.
The <u>base angles have the same measure</u> and the vertex angle has a different measure.
<u>Remember all triangles' interior angles sum to 180°.</u>
If the vertex angle is 42°, then the two base angles combined are:
180° - 42° = 138°
Since the base angles are the same, <u>each base angle is:</u>
138° ÷ 2 = 69°
Therefore the angles in the triangle measure 69°, 69°, and 42°.
The least common multiple of 24 and 36 is 72
The order goes 3, 2, 1, 5, 4 I think.
By subtracting the water poured into the first two beakers from the available water we conclude that the water left for the third beaker is 0.9 liters.
<h3>How to find the water left for the third beaker</h3>
In this question we know that Karen has 3 liters of water and poured 0.7 liters into the <em>first</em> beaker, 1.4 liters into the <em>second</em> beaker and we can determine the water left for the <em>third</em> beaker by subtracted the water poured into the <em>first two</em> beakers from the available water. The available volume is:
V = 3 L - 0.7 L - 1.4 L
V = 0.9 L
By subtracting the water poured into the first two beakers from the available water we conclude that the water left for the third beaker is 0.9 liters.
