The angle subtended by a diameter is a right angle. That's Thales' Theorem (one of them anyway), sometimes thought to be the first theorem of geometry.
So the first choice is true.
The other angles are complementary, not necessarily congruent.
The sides and arcs aren't necessarily congruent either
Answer: first choice
Rises up 3 and run is 2 so your answer is 3/2
Answer:
Liquid R has a mass of of 1 kg at a temperature of 30°c kept in a refrigerator to freeze . Given the specific heat capacity is 300 J kg-¹ °c-1 and the freezing point is 4°c . Calculate the heat release by liquid R.
Step-by-step explanation:

The gfc of both 48 and 32 would be 16
The picture in the attached figure
we know that
<span>The base of a solid oblique pyramid is an equilateral triangle with a base edge length of 14 units
so
AC=CD=AD=14 units
in the right triangle ABC
tan A=opposite side angle A/adjacent side angle A
opposite side angle A=BC
adjacent side angle A=AC
angle A=45 degrees
so
tan 45=BC/14------------> BC=14*tan 45-------> BC=14*1-----> BC=14 units
the answer is</span><span>
the height of the pyramid is 14 units (BC)</span>
