Consider, pls, this explanation + solution:
according to the given equation the centre of this circle is in the poit (6;7) and its radius =4 units.
Using this data, it is possible to define right choice: D.
answer: graph D.
30 members....21 girls and 9 boys
ratio of girls to boys is : 21/9 which reduces to 7/3 or 7:3 or 7 to 3
See the picture attached to better understand the problem
we know that
m ∠ACD=91.5°
m ∠ACD+m ∠ACB=180°-------> by supplementary angles
so
m ∠ACB=180-91.5-----> m ∠ACB=88.5°
m∠CAB+m ∠ACB=90°-----> by complementary angles
so
m ∠CAB=90-88.5-----> 1.5°
m∠ CAB is <span>the new angle at the bottom left side of the door
the answer is1.5</span>
°
Answer:
Step-by-step explanation:
