Here is a right-angled triangle - OCR - GCSE Maths - Question 13 - 2019 - Paper 1

To find angle $x$, we can use the sine function. In a right triangle, the sine of an angle is defined as the ratio of the length of the opposite side to the hypotenuse. Therefore, we have:

$\sin(x) = \frac{\text{opposite}}{\text{hypotenuse}} = \frac{14}{20}$

Calculating this gives:

$\sin(x) = 0.7$

To find angle $x$, we use the inverse sine function:

$x = \sin^{-1}(0.7)$

Using a calculator, we find:

$x \approx 44.427^{\circ}$

Since we need to show that angle $x$ is 35° correct to the nearest degree, we need to ensure we are interpreting the problem correctly and working with the correct values.
