Answer:
Pythagoras theorem states that c²=a²+b²
14²=12²+x²
14²-12²=x²
196-144=x²
52=x²
√52=√x²
7.2111025509279785=x
rounded up to the nearest hundredth=7.21
(9)(3) + 5
27 + 5
32
Your answer is 32.
Answer:
When two lines intersect they form two pairs of opposite angles, A + C and B + D. Another word for opposite angles are vertical angles. Vertical angles are always congruent, which means that they are equal. Adjacent angles are angles that come out of the same vertex
The formula to find the area of a circle is pi x radius^2.
pi = 3.14 (in this case)
radius = 6
6^2 (6 x 6) = 36
36 x 3.14 (radius^2 x pi) = 113.04
So, the area of a circle with radius 6 cm is 113.04 cm.
Answer:
7.
Step-by-step explanation:
21 = 3 * 7
28 = 2 * 2 * 7
42 = 2 * 3 * 7
Collecting common factors:
t is common to all 3 sets of factors so
HCF = 7.
