Answer:

The excess strain and resulting damage from high blood pressure (HBP or hypertension) causes the coronary arteries serving the heart to slowly become narrowed from a buildup of fat, cholesterol and other substances that together are called plaque. This slow process is known as atherosclerosis.

Answer 2

Answer:

Let one angle be x. So, other angle = 90° – x Thus, 2/3 × x = 90° – x or 2x = 270° – 3x or 2x + 3x = 270° or 5x = 270° or x = 270°/5 = 54° So, one angle = 54° and the other angle = 90° – 54°= 36°Read more on Sarthaks.com - https://www.sarthaks.com/790293/out-of-a-pair-of-complementary-angles-one-is-two-third-of-the-other-find-the-angles
