Answer:
below
Step-by-step explanation:
I'm pretty sure this is the answer.
(please open my photo for reference as you read, I am a visual learner/explainer so it will make the most sense that way)
So the first thing you want to do is look at the exterior angle 130°. A straight line is 180°, and every Triangle's angular sum is 180°. How I think of it is that every straight line has a mini protractor on either side. It makes it a bit easier to understand.
180 - 130 = 50
You now know that two of the angles are 50°.
You now have two of the measurements for the triangle farthest to the left.
75° and 50°
75 + 50 = 125
180 - 125 = 55
a = 55°
Now that you have all the measurements for the first triangle, let's move onto the next one.
With two measurements for the second triangle, all you need to do is find their sum and subtract that from 180 and you will have the third measurement!
50 + 60 = 110
180 - 110 = 70
b = 70°
Finally, for the last triangle, you already have two of the measurements 60° and 85°.
85 + 60 = 145
180 - 145 = 35
c = 35°
Sorry if this explanation is a bit messy, it's hard to describe certain things without a letter or some kind of name to differentiate between them verbally.
I hope this helps! <3

Answer:
If i was to read this out loud, i would say: 5 plus the quantity of 17 minus 8.
Step-by-step explanation:
5 + (17-8)
Parenthesis need to be done first! That is why you need to say 'the quantity of...' You also have to add 5 to it all, and you might as well do it before 'the quantity of...' becuz it comes before it in the numerical expression.
YAY! ! ! YOU GOT IT!!! =)
Answer:
58.8
Step-by-step explanation:
basic facts:
-15.4% is the same as 15.4/100
- the word 'of' in maths means times
so 15.4% of the 382ml is the same as
382*15.4/100
to do that, you multiply 382 by 15.4 = 5882.8
then you divide that by 100= 58.828
and then you just round that of to 58.8
