Answer:
the correct answer is 77°
Step-by-step explanation:
Angle GHJ and IHJ form supplementary angles which add up to 180°
therefore angle IHJ=180-154
angle IHJ=26°
Triangle IHJ is an isosceles triangle whose base angles HIJand IJH are equal. Lets assign them the same value, x° each
since the sum of all interior angles of a triangle add up to 180°, then x°+x°+26°=180°
2x+26=180
2x=154°
x=77°
Therefore both HIJ and IJH measure 77°
Answer:

Step-by-step explanation:
Given :-
The sum of two numbers is 1 .
The product of the nos . is 12 .
And we need to find out the numbers. So let us take ,
First number be x
Second number be 1-x .
According to first condition :-

Hence the numbers are 4 and -3
I think it's a3D unless u tell me what u mean by finding S12
