Answer: 7,5.66,39^{\circ}

Step-by-step explanation:

Given

IJ=9\\\angle I=51^{\circ}

from figure, we can write

\Rightarrow \sin 51^{\circ}=\dfrac{HJ}{9}\\\\\Rightarrow HJ=9\sin 51^{\circ}=6.99\approx 7

\Rightarrow \cos 51^{\circ}=\dfrac{HI}{9}\\\Rightarrow HI=9\cos 51^{\circ}\\\Rightarrow HI=5.66

In right angle trianle, the sum of the remaining two angles is 90^{\circ}

\therefore 51^{\circ}+\angle J=90^{\circ}\\\Rightarrow \angle J=90^{\circ}-51^{\circ}\\\Rightarrow \angle J=39^{\circ}

2.1 x 10^5 +4.3 x 10^4
Alla [95]

Answer:

253,000

Step-by-step explanation:

  1. 10^{5} = 100000  
  2. 10^{4} = 10000  
  3. Plug the above answers in: 2.1 × 100,000 + 4.3 × 10,000
  4. 2.1 × 100,000 = 210,000
  5. Plug 210,000 in: 210,000 + 4.3 × 10,000
  6. 4.3 × 10,000 = 43,000
  7. Plug 43,000 in: 210,000 + 43,000
  8. 210,000 + 43,000 = 253,000

I hope this helps!

Each pair of figures below is similar. Find the lengths of all unknown sides​
lions [1.4K]

Answer:

  a) w = 8; y = 5.25

  b) x = 10; z = 7.2

Step-by-step explanation:

a) Dimensions on the smaller figure are FA/F'A' = 3/4 times those on the larger figure.

  6 = (3/4)w

  w = 24/3 = 8

  y = (3/4)·7 = 21/4 = 5.25

__

b) Dimensions on the smaller figure are ER/E'R' = 9/15 = 3/5 times those on the larger figure.

  6 = (3/5)x

  x = 30/3 = 10

  z = (3/5)12 = 36/5 = 7.2
