Answer:
Add the two angles: 43° + 47° = 90°.
Step-by-step explanation:
A right triangle has an angle that equals 90°. Complementary angles equal 90°. Therefore, if you add these two angles, you will know whether or not △ABC is a right triangle. Triangle △ABC is broken up into two angles, m∠ABD and m∠DBC. When the measures m∠ABD and m∠DBC are added together, they equal 90°, and thus, form a complementary angle.

√11 √5 = √(11 * 5) = √55 = approx 7.42 (rounded)
Answer:
5x/2
Step-by-step explanation:
Say the mystery number is "x"
5 times that = 5 * x = 5x
Then the quotient (that means the result of division, so divide!) of that and 2 would give you: 5x/2
Answer:
3/5*8/9=8/15; A
Explanation:
First, you want to multiply both of the numerators together. 3*8=24.
Then, you want to multiply both of the denominators together. 5*9=45.
If you put the numerator and the denominator together, it comes out to be 24/45.
Lastly, you want to simplify 24/45. Divide those both by 3, and you get 8/15.
Hope that helps!
