Is the square root of 3 irrational or rational ?

1 answer:

Since sqrt(3) is not divisible by 2 integers, it is irrational - we can get this due to that it's not repeating nor is it in a discernible pattern<span />

The measure of a base isosceles triangle is 43? what is the measure of the vertex angle

Anestetic [448]

Answer:

The vertex angle is 94 degrees

Step-by-step explanation:

Let the vertex angle be x

Mathematically, the base angles of an isosceles triangle are the same

So if one of the base angles is 43 degrees, then the other base angle would be 43 degrees too

Mathematically, the sum of angles in a triangle is 180 degrees

Thus;

43 + 43 + x = 180

x = 180-86

x = 94 degrees

What is the area of triangle ABC ? round to the nearest square unit ?

mash [69]

Answer: 33 square units

Step-by-step explanation:

Given: Sides lengths of the triangle : 16 units, 10 units, 8 units.

Heron's formula:-

$\text{Area of triangle}=\sqrt{s(s-a)(s-b)(s-c)}$ , where s is the semiperter and a,b and c are the side-lengths of the triangle.

Let a=16 , b=10 and c=8

Then,

$s=\dfrac{a+b+c}{2}=\dfrac{16+10+8}{2}=17$

Using Heron's formula:-

$\text{Area of triangle}=\sqrt{17(17-16)(17-10)(17-8)}\\\\\Rightarrow\ \text{Area of triangle}=\sqrt{1071}=32.7261363439\approx33\text{ square units}$
