1 and 7 because they have the same angles
As a = 0 , there is no sign . Its only 0. Thus the answer is (c)
Answer:
that is really so difficult ? what do you not understand here ? please let me know, if you need any further explanations.
you know what the perimeter is ? if it's the circumference, the way around the object. in other words, the distance you have to walk, when going along all sidelines of the object.
so the perimeter is the sum of of all side lengths.
56 = x - 1 + 3x + 3x + 1 = 7x
x = 8
that gives us the side lengths :
x - 1 = 7 cm
3x = 21 cm
3x + 1 = 22 cm
the formula for the area of a triangle
A = baseline × height / 2
the advantage of a right-angled triangle in this regard is that the sides enclosing the 90 degree angle are already "acting" as baseline and the height (standing on the baseline with a 90 degree angle).
so, we can simply say here, the 3x side is the baseline, and the x-1 side is also the height.
therefore,
A = 21×7/2 = 147/2 = 73.5 cm²
Answer:
3 option
Step-by-step explanation:
The question that can complete the given word problem is, The material comes in pieces of 5 years each. <em>How many </em><em>pieces</em><em> of </em><em>materials </em><em>are needed to </em><em>make a coat</em><em>?</em>
<h3>What question can be formed?</h3><h3 />
You are given the number of yards that are needed to make a coat so the question should be centered around that.
Questions that go best with such information are those that have to do with solving for the number of materials that would be needed to make the coat.
You can therefore supply the length of each piece of material, and then find out how many materials would then be needed to make a coat.
