Answer:
60 & 55
Step-by-step explanation:
1. the sum of the angles 1; 2 and 3 is 180°, then
m∠1=m∠2=m∠3; ⇒m∠3=60°;
2. m∠3=m∠r; ⇒ m∠r=60°;
3. m∠α= 180-(m∠r+65°)°; ⇒ m∠α=55°
all the details are in the picture.
Answer:
24 mm
Step-by-step explanation:
Since it is a right triangle, we can use Pythagorean theorem
where a and b are the legs, and c is the hypotenuse.
We know one of the legs is 10, and the hypotenuse is 26, so we can substitute 10 in for a, and 26 in for c.
Solve the exponents
Now, solve for b. To do this, get b by itself.
First, subtract 100 from both sides
Take the square root of both sides
b=24
So, the other leg is 24 mm
