x + y = -6
Step-by-step explanation:
The approximate measure of angle T in the given diagram is 79°. The correct option is the first option 79°
<h3>Law of Cosines</h3>
From the question, we are to determine the approximate measure of angle T
From the law of cosines, we can write that
cosT = (s² + u² - t²)/2su
From the diagram,
s = 3.9 cm
u = 2.7 cm
t = 4.3 cm
Thus,
cosT = (3.9² + 2.7² - 4.3²)/2(3.9)(2.7)
cosT = (15.21 + 7.29 - 18.49)/21.06
cosT = 4.01/21.06
cosT = 0.1904
T = cos⁻¹(0.1904)
T = 79.02°
T ≈ 79°
Hence, the approximate measure of angle T in the given diagram is 79°. The correct option is the first option 79°

Answer:
$100 rebate
Step-by-step explanation:
$479.99-$100.00= $379.99 or $479.99-20% =$383.99 so the $100.00 rebate a better offer
