Question

A.convert 150 grades into degree

b.find x and y if : (x+3,4) = (6,y)
c.one angle of a right angled triangle is 60 grades. Find the other angles in degree​

Answer 1

To convert 150 grades to degrees, multiply by (9/10). For the equation (x+3,4) = (6,y), x = 3 and y = 4. In a right-angled triangle with 60 degrees, the other two angles are 90 degrees and 30 degrees.

Step-by-step explanation:

(a) To convert grades to degrees, you can use the formula: degrees = grades * (9/10). Using this formula, 150 grades would be equal to 135 degrees.

(b) The given equation is (x+3,4) = (6,y). We can determine the values of x and y by comparing the corresponding components. By comparing the first components, we have x + 3 = 6, which gives x = 3. By comparing the second components, we have 4 = y, which gives y = 4.

(c) In a right-angled triangle, the three angles are 90 degrees, 60 degrees, and 30 degrees. So, if one angle is 60 degrees, the other two angles are 90 degrees and 30 degrees.

Answer 2

Hope it helps

Step-by-step explanation:

a)= 1 grade = 9/10 degree

150 = 9/10 × 150 degree

= 135 degree

b ) = solution

x+3 = 6

so, x = 3

y = 4

c) = let the unknown angle be x

now,

converting 60 grades into degree

= 60×9/10

= 54°

now

54° + 90° + x = 180°

144°-180° = -x

so, x = 36°
