Step-by-step explanation:
why wouldnt i be right!
= (-1/3) + 7/4
= -4/12 + 21/12
= 17/12
Answer:
180°
Step-by-step explanation:
The diagram for this question has been attached to this response.
From the diagram;
(i) ∠2 and ∠6 are equal since they are corresponding angles. This implies that the measure of angle 2 (m∠2) is equal to the measure of angle 6 (m∠6). i.e
m∠2 = m∠6 ---------(a)
But m∠2 = 40°
<em>Substitute this into equation (a) as follows;</em>
40° = m∠6
∴ m∠6 = 40°
(ii) ∠1 and ∠2 are supplementary. This implies that the sum of the measures of angle 1 (m∠1) and angle 2(m∠2) is equal to 180°. i.e
m∠1 + m∠2 = 180° ------------------(b)
But m∠2 = 40°
<em>Substitute this into equation (b) as follows;</em>
m∠1 + 40° = 180°
m∠1 = 180° - 40°
m∠1 = 140°
(iii) The measure of ∠1 + ∠6 is given by;
m∠1 + m∠6
<em>Substitute the values of m∠1 = 140° and m∠6 = 40° into the expression to get</em>
m∠1 + m∠6 = 140° + 40°
m∠1 + m∠6 = 180<em>°</em>
<em />
Therefore the measure of ∠1 + ∠6 is 180°
Sorry this is just for points
Answer:
Option 4
Step-by-step explanation:
So we know that the area of a square is found by s^2. This means that we can just look for (6r)^2, since 6r is our side length! Let's see...We know that (6r)^2 is equal to 6^2 times r^2 because of the distributive property of exponents. Therefore, option 4 is our right answer. 36 is 6^2 and r^2 is r^2.
