This can be solve by establishing equations.
let x be the miles mrs. storey drove
y be the miles mr storey drovee
the first equation is
y = 3x
second equation
x + y = 3200
then substitute equation 1
x + 3x = 3200
4x = 3200
x = 800 miles mrs storey drove
y = 3x = 2400 miles mr storey drove
The measure of angle 2 is 
Explanation:
Given that 
and 
are complementary angles.
Also, the measure of angle 1 is 
We need to determine the measure of
Since, we know that the complementary angles add up to 90°, then the angles and add up to 90°.
Thus, we have,
Substituting the value of in the above expression, we have,
Subtracting both sides by 76°, we get,
Simplifying, we have,
Thus, the measure of angle 2 is
<u>Definition of research proposal:</u>
A research proposal is a document in which a research project is proposed, usually from a scientific or academic community, and usually asks for funding for this research. Proposals will be assessed in the light of the costs and potential impacts on the proposed study and the feasibility of the proposed implementation plan.
The main usage of the research proposal is to satisfy the reader about the value of the project and specialist knowledge. One must demonstrate that he/she has a work plan and that his/her project will succeed. It involves various types: pre-proposals, unsolicited (submitting without any prior request) and solicited (submitting proposals in response to the request).
