Area of triangle = 1/2 × base × height
so,
24=1/2*base*4
base=12m
The answer is x=6. Hope this helped.
Answer:
4,7025 (kJ).
Step-by-step explanation:
1) according to the condition: m=25 gr.; t₂=90; t₁=45; c=4.18 J/(g°C);
2) the formula of required heat is
Q=c*m*(t₂- t₁);
3) according to the formula of heat:
Q=4.18*25*45=4702.5 (J).
Answer:
2.91 units
Step-by-step explanation:
If and only if this is a right triangle, we can apply the some fimctopm to determine the length of side BD:
side BC
tan 20 degrees = ---------------
8
or side BC = 8 tan 20 degrees. Since tan 20 degrees = 0.364 radians,
side BC has length 8(0.364) = 2.91 units
Answer:
The distance between the points (4,3) and (1,-1) is C. 5 units.
