The answer to this is x^2 + 2x - 5
It would be the last option. I just worked the problem out and figured it out. I hope this helped! (:
Answer:
/2=1.41
/5=2.24
(a)^2+(b)^2=(c)^2
(1.41)^2+(b)^2=(2.24)^2
2+(b)^2=5
(b)^2=5-2
(b)^2=3
b=/3 or 1.73
Step-by-step explanation:
for a triangle, a missing value of the side can be found using pythagorean theorem which is (a)^2+(b)^2=(c)^2
replace it with the given value.
*note:(c)^2 should be the hypotenuse
inverse of +ve is -ve
inverse of square is square root
The measure of angle 3 from the figure is 110 degrees
<h3>Lines and angles</h3>
An angle is the intersection between two lines. From the given figure, we have the following parameters
m∠1= 40°,
m∠2= 70°.
Required
Measure of angle 3
The sum of the interior angles of the triangle is equal to the exterior
Sum of interior = <1 + <2
Sum of interior = 40 + 70
Sum of interior =110 degrees
Hence the measure of angle 3 from the figure is 110 degrees
