1. 50 degree angle I believe
2. 150 degree angle
3. 45 degree angle
Sorry if this doesn't help but, with no context about the answers they have given you I can't fully help. Try using a protractor like this down below.
Have a good day!
Answer:
for question 9 is not that hard
Step-by-step explanation:
take the 8% and just get rid of the percentage away and add a decimal like this 8. then you move it back which should make this 0.8 hope this helps for that section
Answer: 2.325 meters
Step-by-step explanation:
The roof of a lean-to-garden shed has a gradient of 0.35.find the height....they have given the base as 1.5m and a shorter height 1.8m its like a house
-------
It sounds like you have a right triangle with base = 1.5,
----
Use a proportion to get:
(height of that triangle)/1.5 = 35/100
height of that triangle = 1.5*0.35 = 0.5250
-----
greater height of the lean-to = 1.8 + 0.5250 = 2.325 meters
I'm pretty sure you would multiply the cost amount to the percentage
