Answer:
James is correct
Step-by-step explanation:
Given the expression wrote by a meteorologist as 78 + (-6), If James believes that this expression is the same as 78-6 then James is correct because if the parenthesis is expanded the product of the addition and the subtraction sign will produce a negative sign i.e + * - = -
78 + (-6) = 78 - 6 = 72
Based on the conclusion, we can say that James is correct in his reasoning
Answer:
D. m∡1 = 36°; m∡2 = 18°; m∡3 = 72°
Step-by-step explanation:
The 10 central angles are all the same for the regular decagon, so each is 1/10 of 360°. Angle 1 is 36°.
Angle 2 is half of angle 1, since the altitude shown is an angle bisector. Angle 2 is 18°.
Angle 3 is the complement of angle 2. It is the other acute angle in the triangle that has angle 2 marked. Angle 3 is 72°.
