Step-by-step explanation:
The area of triangle is
=21×height×base=21×3×4=3×2=6 cm2
Answer:
6x214=1284
1284-3 is 1281
Step-by-step explanation:
The original number to the nearest tenth is 23.8
Answer:
Step-by-step explanation:
The exterior angle is 151 degrees. The theorem states that the sum of its 2 remote interior angles, 5x+3 and 9x-20, will add up to this exterior angle. Therefore,
5x+3+9x-20 = 151 and
14x - 17 = 151 and
14x = 151 + 17
14x = 168 so
x = 12
If you want to find out the measure of each of these angles, just plug in 12 for x and do the math:
5(12) + 3 = 63 and
9(12) - 20 = 88 and
88 + 63 = 151 as it should.
Answer: 10y+5x=50
Step-by-step explanation: $10 times y + $5 times x =$50
