Answer:
1) 14
2) 18
3) -6
4) 2
5) 80
Step-by-step explanation:
1) (2)(2)+4-(3)(-2) = 14
2) (3)(2)(4)-3(2) = 18
3) (6)(4)/(2)(-2) = -6
4) [(2)(4)-(2)(2)] +(-2) = 2
5) (-5)(2)(4)(-2) = 80
Answer:
The tree is about 8 feet.
Step-by-step explanation:
7 2/3 = 7.6 as a fraction.
30 1/5 = 30.5 as a fraction.
Know, we must divide 30.5 by 7.6.
30.5 ÷ 7.6 = 4 when rounded to the nearest whole number.
Since we know that the stake is 2 feet, we must multiply this by 4, since the other shadow is 4 times the amount of the stake.
2 x 4 = 8
This means the tree is about 8 feet.
Answer:
Step-by-step explanation:
Sum of angles of a triangle = 180
So, 56 + 58 + x = 180
114 + x = 180
x = 116
Now ∠ 1 + ∠x = 180 [ straight line angles]
∠ 1 + 66 = 180
∠1 = 180 - 66 = 114°
OR
You can use the rule : Exterior angle = sum of 2 interior opposite angles.
56 + 58 = ∠1
114 = ∠1
