Answer:
1) 46.6
Step-by-step explanation:
Given Data:
s1 of Triangle ABC= 4cm
s2 of Triangle ABC=6cm
s3 of Triangle ABC=8cm
As per the side-side-side SSS of a given triangle
the corresponding angles are found by the following law of cosine formula
cos A = (b2 + c2 − a2) / 2bc
Putting the values we get
cos A= (4^2+8^2-6^2)/2(4)(8)
cos A= (16+64-36)/64
A=cos^-0.6875
A=46.57!
Answer: First option.
Step-by-step explanation:
1. To solve this problem you can applly the quadratic formula, which is shown below:

2. The quadratic equation is:

3. Then:
a=1
b=-4
c=-38
4. Therefore, when you substitute these values into the quadratic formula, you obtain the following result:

x=2±√42
