Answer: The first graph.
This can be found by looking at the y-intercept and plugging in values for x.
Answer:
(3 x 10^6) + (3 x 10^5) + (7 x 10^4) + (0 x 10^3) + (0 x 10^2) + (6 x 10^1)
Step-by-step explanation:
Answer:
135°
Step-by-step explanation:
angle x spans throughout two angles, 75° and 60°, so it is the sum of the two. It could not be any of the answers you gave.
We know that
[surface area of the triangular pyramid]=area of the base+3*[area of lateral triangles]
area of the base=12*8/2-----> 48 cm²
area of one lateral triangle=12*10/2-----> 60 cm²
[surface area of the triangular pyramid]=48+3*[60]-----> 228 cm²
the answer is the option
<span>B) 228 cm2</span>
