Answer:
36°, 54°, 90°
Step-by-step explanation:
2:3:5 equal 10 parts in total
there are a total of 180 degrees in a triangle
180°/10 = 18°
2(18°) = 36°
3(18°) = 54°
5(18°) = 90°
Answer:
The numbers are: 1 and 3.
Step-by-step explanation:
Let the first number be and the second number be .
Given: The difference between twice the number and the second number is . writing this mathematically,
From the second statement we get:
Solving for and we get:
and
Thus the first number is 1 and the second number is 3.
Answer:
D
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = ( - , ) and r = , thus
(x - (- ))² + (y - )² = ( )², that is
(x + )² + (y - )² = → D
