Answer:
Both angle 1 and 3 are 52 degrees
Step-by-step explanation:
if angle 6 is 128, then so are angle 2, 4, and 8.
if angle 2 is 128, and the whole line is 180, then the missing angle (angle 1) must be 52.
angles 1 and 3 are equal
Answer:
It's (a).
Step-by-step explanation:
Y ≥ 1:
The line y = 1 is a horizontal passing though the point on the y axis where y = 1 and y ≥ 1 is the area above this line,. The area is shaded above this line,
Y ≥ x - 1:
The line y = x - 1 is a line which rises to the right with gradient 1 and which passes through the point (0, -1) on the y axis. Y ≥ x - 1 is the area above the line and is shaded.
The combination of these 2 inequalities gives us diagram (a). The shaded part satisfies both inequalities.
Answer:
47.6 cm
Step-by-step explanation:
Since the triangle is equilateral then the 2 inclined sides = 7.2 cm
Perimeter is then the sum of the 5 sides
P = 13 + 7.2 + 13 + 7.2 + 7.2 = 47.6 cm
