We have to find the correct statement for angle A in a triangle ABC,
which is an obtuse triangle. We know that angle B is obtuse ( greater
than 90 degrees ). Therefore angles A and C must be less than 90
degrees. Angle A can not be congruent to angle B ( angle B > angle A
). It can be congruent to angle C but just in case that ABC is an
isosceles obtuse triangle. Answer: Angle A must be A ) less than 90
degrees.
Answer:
12√2.
Step-by-step explanation:
You can do this by the Pythagoras theorem:
20^2 = x^2 + (4sqrt7)^2 where x is the distance required.
x^2 = 20^2 - (4sqrt7)^2
= 400 - 112
= 288
x = √288
= √144 *√2
= 12√2.
the fact is you cant copy and paste it you have to take screenshot or picture and attach it i don't understand the the computers substitution for unknown characters
