Answer:
x = -11
Step-by-step explanation:
0.2(20x + 10) = -42
4x + 2 = -42 Distribute 0.2 to the numbers in the paranthesis
4x = -44 Add 2 to both sides
x = -11 Divide 4 from both sides
Answer:
find below
Step-by-step explanation:
5(x-7)=20
5x-35=20
5x=55
x=11
Answer:
B. 1,486 metres
Step-by-step explanation:
Find the area of the triangle.
60 x 60 = 3600
3600 ÷ 2 = 1800
Area of triangle = 1800 metres
Area of unshaded circle is approximately 314 metres square using pi
1800 - 314 = 1486
1486 metres square is the approximate area of the shaded region.
Answer:
Option (D) is correct.
Step-by-step explanation:
In a triangle BCD , with b, c, d as the sides of triangle.
Sine rule states when we we divide side b by the sine of angle B then it is equal to side c divided by the sine of angle C and also equal to side d divided by the sine of angle D.
Using Sine rule,

Consider the first and third ratio,

Substitute the values of d = 3 , b= 5 and ∠D=25°

Thus, Measure of angle B is 45 and 135 as sinB is positive is first and 2nd quadrant.
Thus, option (D) is correct.
