17.5cm squared
Explain: rectangle 7x5= 35
as this triangle is half of a 7x5 rectangle
35 divided by 2 = 17.5
You can cross multiply for this problem. So:
So K=35!
Hope this helps! :)
If these two triangles are similar, the ratio of the side length 5 to the side length 8 should be the same as the side length x to the side length 10. In other words, x=6.25. Hope this helped!
Answer:
Here you go, I think
Step-by-step explanation:
Answer:
To the nearest tenth = 10.8cm
Step-by-step explanation:
Using the cosine rule
J² = i² + k² + 2ikcosj
J² = 3.4² + 7.7² + 2(3.4)(7.7) cos 30
J² = 11.56 + 59.29 + 52.36cos30
J² = 11.56 + 59.29 + 52.36(0.8660)
J² = 11.56 + 59.29 + 45.35
J² = 116.2
J=√116.2
J= 10.78 cm
To the nearest tenth = 10.8cm
