Aside from the conventional formula for triangle, A=<span>½bh which is only applicable to problems where the base and height are already given and the triangle is a right triangle having a degree of 90. There are some formulas in getting the area of a triangle:
>Given three sides of the triangle, use Heron's Formula
A= sqrt(s(s-a)(s-b)(s-c))
s= (a+b+c)/2
>Given two sides with an included angle
</span>Area = <span>1/2 </span><span>ab sin (tetha)
</span><span>tethat should be in degrees
</span>
For number 11 the third angle would be equal X as the second angle is, since the two sides next to the those angles are congruent. Then you would have to set an equation saying that 2x + 38= 180 and then you can just solve for X
Answer:
1
Step-by-step explanation:
Follow the signs rule:
IF:
There is a + sign, and the number directly next is +, add
There is a + sign, and the number directly next is -, subtract
There is a - sign, and the number directly next is +, subtract
There is a - sign, and the number directly next is -, add
In this case, there is a plus sign, and a negative sign, therefore, subtract:
5 + (-4) = 5 - 4 = 1
1 is your answer.
