Answer:
valid based on the given information. If not, write invalid. ... So, the statement is invalid. Determine .....disprove a conjecture reached using inductive or deductive .
Y=sin(? when ?=0° the answer is 0
Y=0
Answer:
yes because radius makes 90 degree with it. using Pythagoras theorem, it is seen that 5^2 = 3^2 + 4^2

The base angles are both 74°
Further explanation:
An isosceles triangle is a type of triangle that has two sides and two angles equal.
Let A, B and C be three angles
Let A=32°
If A is 32 then B and C will be equal
The internal angles of a triangle are 180°
So,
m∠A+m∠B+m∠C=180°
We know that B and C are equal
m∠B=m∠C
So putting the value of A and replacing C by B
32°+m∠B+m∠B=180°
32°+2m∠B=180°
2m∠B=180°-32°
2m∠B=148°
m∠B=148°/2
m∠B=74°
As
m∠B=m∠C
So
m∠C=74°
The base angles are both 74°
