Answer:
Part 1) The measure of angle A is 
Part 2) The length side of a is equal to 
Part 3) The length side of b is equal to 
Step-by-step explanation:
step 1
Find the measure of angle A
we know that
The sum of the internal angles of a triangle must be equal to 180 degrees
so

substitute the given values



step 2
Find the length of side a
Applying the law of sines

substitute the given values



step 3
Find the length of side b
Applying the law of sines

substitute the given values



Let's solve your equation step-by-step
6v^2+v=40
step 1: subtract 40 from both sides
6v^2+v-40=0
6v^2+v-40=0
Step 2: factor left side of equation
(3v+8)(2v-5)=0
step 3: set factors eqyal to 0
3v+8=0 or 2v-5=0
Answer is v= -8/3 or v= 5/2
To find the volume of a cone,
multiply 1/3 of it’s base times it’s height.
1/3 of 8 = 2.7
2.7 x 8 = 21.6 cubic yards
The sum of all the angles in a triangle should always add up to 360° and seeing that this is an isosceles triangle 2 of the angles should be equal.
So there would be 2 30° angles and 360-60=300 so the 3rd angle would be equal to 300° . Hope this helps!
Additive inverse means the sum should be 0
so all you gotta do is multiply the complex number by -1
