Answer: I cant see the picture.
Explanation:
1. Supplementary angles : Two angles are supplementary if their sum is 180°.
For angle 1 and ∠COF to be supplementary,
∠1 + ∠COF =180°
must be satisfied.
We see in the figure that angle 1 and COF form a straight line.
The angle of a straight line is 180°.
∴ 1 is a supplement of ∠COF.
Answer : YES
2. Given : ∠COF =150° ;
AD is perpendicular to BF.
Here, ∠BOC + ∠COF = 180° , since they form a straight line.
∠BOC = 180° - ∠COF = 180° - 150° =30°
∴ ∠BOC = 30°
Answer : D. 30°
The correct answer is C. Reading and literacy rates, health care facilities, and gross domestic product.
Explanation
The Human Development Index is a measure that summarizes human development in a given country from three basic aspects that are:
Life expectancy, which is summarized as having a long and healthy life from the moment you are born; The level of literacy, is the knowledge that is measured from the adult literacy rate and the combination of the gross enrollment rates of primary, secondary and tertiary; the last indicator is the country's GDP per capita. Therefore, the correct answer is C. Reading and literacy rates, health care facilities, and gross domestic product
Answer:
we know that sum of all angles of triangle is 180
let angles be 5x , 6x , 7x
now sum of angles : 5x + 6x + 7x = 18x = 180
therefore we got x : 10
therefore angles : 50 , 60 , 70
