Answer:
Step-by-step explanation:
An isosceles triangle has 2 sides that are the same length. Let's say that our triangle has the 2 sides measuring the same and the base is a different length. The vertex angle is the top angle. By the definition of an isosceles triangle, since the 2 sides measure the same length, then the angles across from those sides have the same degree measure. If we know the measure of the vertex angle, then we have
180 = vertex angle - base angle - base angle
but since the base angles are the same and we have 2 of them, then
180 = vertex angle - 2 base angles
For example, if the vertex angle measures 80 degrees, then 180 - 80 = 100. That 100 has to be split in half for each of the base angles which are the same as each other. So the vertex angle is 80 and each base is 50.
The most used fractions on a number line used before 1 are 1/4, 1/2, 1/3, 2/4, 2/3, and 3/4.
Answer:
273 m^2
Step-by-step explanation:
Firstly, you should find the area of the triangle. Remember that the formula for a triangle's area is (Base x Height) ÷ 2
Therefore,
11 x 14 is 154
154/2 = 77 m^2
Then, we find the area of the square which is just Base x Heigh
14 x 14 is 196m^2
And finally, we just add the two
77 + 196 = 273 m^2
The reason it's not m^3 is because we're not dealing with a third dimensional figure.
Btw, ^ means to the power of.
