8×30=10×z
10z=240
z=24
Hence the value of z is 24
I would go with 45,45, 90 because first you can eliminate C and D.
C because it is not an equilateral triangle and D because you can figure it out.
Now you have A and B. A 30, 60 90 Degree Triangle would mean that none of the sides are equal (or the legs don't equal the hypotenuse when you put it in Pythagorean form [a²+b²=c²]). However if you translate the problem to answers that are easier to understand: {(7√3 = 12.124)² + 21² = 587.8944 = 14√3} Then you can see, two angles are equal to each other. So the answer is B.
Answer: B
Step-by-step explanation:
Multiply 4 x 8 which is 32.
Then divide it by 1/2.
The answer is 16.
I'm sorry, do you have any more detail. i'm not sure what this means?
