Answer:
The cosine of the angle is <u>positive</u>
The sine of the angle is <u>negative</u>
Step-by-step explanation:
We are given that
angle lies in fourth quadrant
and we know that
In first quadrant:
sin is positive
cos is positive
In second quadrant:
sin is positive
cos is negative
In third quadrant:
sin is negative
cos is negative
in fourth quadrant , cosine of angle is always positive
and sine of angle is always negative
so,
The cosine of the angle is <u>positive</u>
The sine of the angle is <u>negative</u>
Answer:
The two column proof can be presented as follows;
Statement
Reason
1. RUST is a rectangle
Given
2. RU = ST ; UT = RS
Definition of a rectangle
3. ∠STU and ∠SRU are right angles
Definition of a rectangle
4. ΔURS ≅ ΔSTU
By SAS rule of congruency
5. ∠USR = ∠SUT
By CPCTC
Step-by-step explanation:
Given that the side RU, the angle ∠SRU and the side RS of triangle ΔURS are congruent to the side ST the angle ∠STU and the side UT of triangle ΔSTU, then ΔURS is congruent to ΔSTU, by the Side-Angle-Side (SAS) rule of congruency
Therefore, we have that ∠USR ≅ ∠SUT and therefore, it can be shown that ∠USR = ∠SUT using the Congruent Parts of Congruent Triangle are Congruent (CPCTC) postulate.
Answer:
23.17%
Step-by-step explanation:
The project costs $15,880 of which you contributed $3,680. To know the percentage of how much you finance,
(amount paid / cost)*100%
= (3680/15880)*100%
= (0.231738035)*100%
= 23.1738035%
Thus the amount contributed is 23.17% of the cost.
Answer:
personally none but it would be 35%-25%
