If your solving for t then t = 4.5

For the first one, you take the original temprature -3.0° and add -5.4° which gives you an answer of -8.4°c :)

for the second you add the amount for breakfast and lunch, then multiply by 7 days
Answer:
true?
Step-by-step explanation:
what were you looking for exactly... but it is true

Answer:
The nearest degree of the angle between the 8cm and 9cm sides is:
Step-by-step explanation:
To obtain the correct angle in a small triangle like the triangle formed with the measures in the exercise is a little bit hard, in a change of this, I used a triangle calculator, with this I obtained the right angle formed by the sides with 8 cm and 9 cm, which I'm gonna add like an attachment.
From this image, you can guide yourself to draw the triangle without mistakes and to identify the right angle, which is 40,8° but the compass is not so defined, by this reason you can take it like 41° or 40°.
