Answer:

20°

Step-by-step explanation:

We know that:

-4 + x = 16 [x = difference between two temperatures]

Solution:

-4 + x = 16
=> x = 16 + 4
=> x = 20

Hence, the difference between the two temperatures is 20°.

If arc SQ = 84° and ∠RPS = 26°, what is the measure of arc RS? need answer asap thank you

Lera25 [3.4K]

Answer:

$arc\ RS=136\°$

Step-by-step explanation:

we know that

The measurement of the external angle is the semi-difference of the arcs which comprises

In this problem

m∠RPS= $26\°$ ------> external angle

m∠RPS= $\frac{1}{2}(arc\ RS-arc\ SQ)$

we have

m∠RPS= $26\°$

$arc\ SQ=84\°$

substitute the values

$26\°=\frac{1}{2}(arc\ RS-84\°)$

Solve for arc RS

$52\°=(arc\ RS-84\°)$

$arc\ RS=52\°+84\°=136\°$
